That Guy –
I am not being paid or solicited for this review and am in no way affiliated with worksharp, I’m just a very satisfied customer. I’m going to respond to the points of the 1 star review written by Sandh (referred to from now on as “the review”), and I’m doing it mainly because when I research something, I read the 1 star reviews along with 5 star to see why they were given to look for trends or QC issues. I bought this early Feb 2021 and before reading the review, I was certain that it was going to be missing pieces or some other failed QC. This is not a knock on worksharp’s QC, it’s because I couldn’t imagine anyone that has put hands on the device and used it to sharpen a knife giving it a one star review.Let’s get started. I’m going to copy his numbered complain below in quotes ” and then I will follow up my comment starting and ending with 5 stars *****”1) Base does not have enough grip to keep it from sliding around on the work surface unless you hold it down with one hand. Really? This does not leave a hand free to control the blade, though one could argue keeping your hand away from the blade is not a bad thing for safety. But, see my next point. It would be nice to have an accessory table clamp, removable/optional suction cups, or a more aggressive tread with softer rubber on the feet that won’t fill and load down with even minor dust and becoming slippery.”*****I actually almost agree with this point. I expected the base to be a bit heavier, especially after watching the worksharp demo video where the guy talks about how hefty the base is. It’s pretty light and hollow on the bottom. I’m considering trying to see if I can 3d print a solid plastic piece that will snap into the void to add some weight to it. The rubber feet are good, but having a clamp accessory or suction cups would be nice. I sharpen on a mat so I can’t speak to whether or not a minimal amount of dust will make them slippery on a table but on the mat it was not an issue. This is definitely not a one handed sharpener. You will have to either hold the sharpener base or the knife handle while using it. I’m not sure why you would need to control the blade when it is clamped into the system, or even what you would do to control it other than hold onto the sharpener base or the knife handle.*****”2) I’m a little concerned with the direction of travel for the stone being engineered into the edge of the blade with no practical guard on a small curved top stone assembly. This shows very poor engineering controls for safety and would be an OSHA violation in any industrial environment. IF you keep your fingers carefully placed on the very small curved top grip, your fine, BUT, if you happen to let your finger slip over the edge even a little, particularly if your hands are wet or sweaty, you’re likely going to lose the end of your finger. Given how long I can see people potentially using this on large blades, or when sharpening a number of blades, and the likelihood of hand fatigue occurring, a moment of inattention could have dire results. There should be a finger stop that’s curved away from the blade rather than towards it, and/or a surface that is not a smooth hard plastic that has a texture to grippy surface.”*****Looking at the design of the stone carriage, I was a little concerned before purchase. It looks like it would be very awkward and I too was concerned that a tiny slip could end up with an ER visit for stitches. When holding the handle, there is plenty of room between your hand and the blade to feel safe while sharpening. You would almost have to be intentionally pointing your fingers downward to contact the blade during the push stroke. If your hands get so tired that your fingers are hanging down like that, you need to take a break anyway. No system, sharpening or otherwise, would be safe with your hands that fatigued and that close to a sharp blade.*****”3) Magnet assembly that holds the rod end ball pin is way too feeble and continually drops the rod/stone assembly, suddenly affecting the angle of grind, every couple of stokes. This is made worse due to the next issue;”*****The only time that I had this problem was when I purposefully pushed down hard trying to make this happen. I wanted to see how hard I could push before the magnet came loose because I didn’t trust it. The instruction video says light strokes and light strokes work just fine.*****I’m going to address points 4 and 5 together:”4) Either the pin is undersized or the hole for the pin at the magnet is oversized. This results in wobble of the pin during use. Because the magnet is so weak, any break or change of the angle or flat surface contact between the end of the pin and the magnet, breaks the magnet’s contact and reduces it’s hold. This is potentially made worse by;5) There is an o-ring/bushing on the base of the pin at the ball end to limit how far the pin can insert into the magnet hole. If this slips up on the pin even very slightly, it prevents the pin from making contact with the magnet, resulting in a gap that further limits the hold of the magnet. I assume this intended to buffer the contact a little when inserting the magnet as banging something against a neodymium magnet, or exposure to heat, will cause a loss of magnetism. If they are going to use something to buffer contact at all, it needs to be glued or inserted into a recess on the pin to prevent or limit movement. Currently it slides in place freely though with some friction, so it can easily block or prevent proper full insertion of the pin.”*****Mine doesn’t have an O-ring at the base of the pin. It’s just a rod end bearing that fits snugly in the hole with a pretty strong magnet. Maybe this is why his experience with how well the rod stays stuck to the magnet is so different than mine. I thought that maybe mine came off and I didn’t notice, but the picture on the website does not show any bushing on that piece either. Sandh, if you by chance read this, maybe try taking that bushing off and see if it helps with this issue.*****”6) The rotating cup/receiver for the blade holder assembly does not seat properly in the locked position, allowing both side to side, up and down and rotational wobble. On mine, with excessive force, I can push it in hard while wiggling it around and eventually it will seat firmly but this is a pain to do every time you rotate and reposition the blade or change the angle.”*****This is not a problem that I have. The blade holder does allow for a little bit of up and down wobble with a lot of pressure, but none side to side. You can actually see the stones flex inside the stone holder before you have pushed hard enough to make the blade holder wobble. Again light pressure mostly mitigates either of these problems.*****”7) This does not work AT ALL for small Case or similar sized small pocket blades. You simply cannot seat the blade back into the holder for the rear of the slot to make contact with the spine or the blade won’t protrude far enough to make contact with the stones. Even IF you clamp the blade down at the very tip of the jaws near the spine of the blade, the stone will make contact with the top of the blade holder at every angle you would likely need to use. It would be nice if they supplied a small adapter for small width blades that allowed for clearance of the stone…but they don’t.”*****This is accurate. There needs to be an adapter for small blade knives. I also had trouble sharpening a small pairing knife. I was able to in the end, but I had to use a steeper angle than I wanted to so that I wasn’t hitting the clamp with each stroke. I also couldn’t sharpen the small blade on my Victorinox pocket knife.*****”8) I find the ceramic to load up pretty quickly and lose much of its abrasion. Given the small surface area of the stone, this becomes an issue fairly quickly. I believe this is inevitable given its size and since you are only supposed to use this dry. So, this required regular cleaning with water, possibly with some cleaner, and drying, during a single use depending on how much material was involved; size of blade, etc. Perhaps if you don’t allow your blades to become dull and resharpen regularly this would be less of an issue as less material would need to be removed for a quick touchup. It would be nice if they provided specific instructions on how to do this;”*****The day I got this sharpener, I sharpened 3 pocket knives (one with 2 blades)to a mirror finish, 7 kitchen knives, and a Mora fixed blade carbon steel knife all in one sitting. Then I took it with me to work and sharpened another pocket knife there to a mirror finish and then when someone asked how easily the stones cleaned up, I actually cleaned the stones. You can decide if you will need to stop and clean the stones while sharpening your knives.*****”9) Mine didn’t come with any instructions. Perhaps that was a quality oversight. They have videos, also on Youtube, that explain usage and mention that you need to clean it, but seem to lack specifics. I found that a Mr. Clean Eraser pad with a drop of dishwashing soap, followed by a thorough rinse, worked really well to remove virtually all of the material from the stone, but this requires getting the assembly wet. I’ve not seen rust yet, but I have had residue on the rod create some friction in the stone movement that needs either additional cleaning on the rod itself or a drop of lubrication to mitigate.”*****Mine had an instruction booklet. Between that and the O-ring, I would say that it is possible that Sandh may have gotten a unit that slipped through the cracks of the QC team. Given how drastically different his experience is than mine there isn’t much else that really makes sense.*****”10) The ceramic stone appears to be too soft and is quickly getting small scratches, beyond typical expected surface wear, from burrs left from the previous grit. It would appear that they need an interim grit or harder ceramic. I can see that the stones will need regular replacing eventually. Built in obsolescence to require repeat purchases I suspect. Given supply issues and that they’ve yet to release additional grits, I anticipate this will become a real issue with regular use…except that given all the above issues I find this practically unusable so won’t be using it much if at all going forward.”*****While I disagree that the ceramic stone is too soft and is getting scratched beyond normal expected wear and tear, I do agree that there needs to be another grit between the 600 grit diamond stone and the ceramic. It takes a long time to get a mirror finish on the ceramic after coming off of the 600 grit stone. I would also like to see more grits available.*****There you have it. Two drastically different experiences with this product laid out side by side. I would like to see more grit options and an adapter for smaller blades. I would also like to see an adapter for scissors and maybe even one for axes. I would like to see a heavier base or an optional base that clamps to the table. It is excellent for large pocket knives and kitchen knives as is and if that is what you are trying to sharpen, it will work perfectly for you.
Deepstar Run –
Iβm a 48 year old woman who wishes she was more outdoorsy and capable with this kind of thing. My mom came to visit and I found my expensive Wustoff knife in the dishwasher. Itβs never been the same. So, I watched and old movie that showed a Scottish warrior using a stone to sharpen his sword while lounging on his furs and thought, βHey, I can do that!β Guess what? I bought a flat whetstone ($80 for a 2 sided slab of rock!) and even with YouTube videos and stacking coins to get the right angle, my kitchen knives remained depressingly dull. Since itβs very difficult for me to even find someone to sharpen knives professionally and really expensive when I do, I decided to try one last time and give Work Smart a shot. Iβm so glad I did! I didnβt get a βmirror finishβ but it was definitely sharp enough for me. Advice:1. Read βThat Guyβ review. Even though I didnβt understand half of what he said initially- it helped me out a lot when I actually got the product.2. Donβt just read the instructions or watch the video attached to this Amazon page. Even with the pics. I scratched up the surface of my knife because I stroked from top to bottom instead of sawing back and forth at first. (I didnβt understand the super obvious pic.)3. Itβs easy to get distracted and forget how many strokes and which side youβve done. I grabbed a marker and wrote 1 on one side of the clamp and 2 on the second side since I wasnβt flipping the arm. (No white marker to tell you which side youβre on.) I also kept count on a piece of paper.3. This takes a loooong time with a dull knife. Just getting a tiny βburrβ on the first step took at least 20 swipes and I was a little uneven at first so the top of the knife didnβt have a burr until I did it again. You canβt go fast and be sure to use light pressure. If youβre catching on the edge too much or the base is rocking, youβre pressing too hard. Make sure the base stays in the same position and doesnβt start going sideways. My Wustoff took over an hour. 4. For the leather strop, I just used the inside of a belt- that little strip of leather is too flimsy.5. I couldnβt tell by sight that the knife was sharp. Try to slice through paper.6. MOST IMPORTANT- You now have a sharp knife! Donβt do the dumb stuff you used to do when it was dull- you know, like try and catch it when it falls off the counter. Seriously, I felt a lot less badass with my sharp blade when I was applying the bandage to my thumb!
