Tri-angle Sharpmaker 204MF
About the Product
The key to sharpening any cutting tool is removing the steel at the edge while maintaining a consistent angle between the blade and the stone. Spyderco’s Tri-Angle Sharpmaker takes the mystery out of this process and enables anyone to sharpen a knife effectively with just a few minutes practice. Its durable ABS plastic base contains keyed holes that accurately set the stones’ sharpening angles at a 30° (15° each side) or 40° (20° each side) for sharpening knives.
The 4-Stone Deluxe Diamond Controlled-Angle Sharpening System ensures that your knife edge sharpens to the exact bevel you specify. Designed to give your blade a professional, razor sharp edge every time, regardless of your sharpening ability. Excellent for beginners and advanced users alike. The original and legendary Controlled-Angle System is the ultimate in Knife Sharpening technology.

What customers say about "Key Specs"
Spyderco Tri-angle Sharpmaker 204MF Knife Sharpener
  • The stones are of a high quality. this is all you'll likely need to maintain a razor-sharp edge on most of your kitchen and sporting knives.
  • Triangle ceramic rods (allows you to sharpen serrated edges: haven't tried this yet). Sockets on bottom for 2 rods to lay flat to create a sharpening stone: haven't tried this yet, but it is a good feature
  • Easy enough for anyone to use and comes with great instructions. Gets knives razor sharp and keeps them that way.
  • Difficult to sharpen knives that are chisel ground and only have one edge (such as Emerson knives).
  • The con is that it does not work on dull knives.
Lansky LKDMD 4-Stone Deluxe Diamond Knife Sharpening Kit
  • The courser diamond stones are very aggressive and excellent at re-profiling edges. This system made easy work of the 50 Rockwell broadheads I took 5° off of. And the medium and fine grit stones finished the broadheads with an excellent edge that was sharp and durable.
  • It cuts the sharpening time in 1/2 from the regular stone system. The extra course stone I rarely use (made for reprofiling). This system plus the Ceramic stone (yellow) is a great Combo.
  • Diamond over stone. I have had it for a year or so with no real signs or wear.
  • For larger knives (e.g. anything longer than about 5-6 inches, the system is going to need to be adjusted very frequently to handle the entire length of the blade. It's really rather small.

What customers say about "Sharpening"
Spyderco Tri-angle Sharpmaker 204MF Knife Sharpener
  • Easy to sharpen at the desired angle recommended by Spyderco.
  • Getting the edge angle right is much easier, which is why I got it. I think I'll use this more vs my electric knife grinder.
  • The double angle 30 vs 40 is great I have a few wide blade knives and this made a huge difference.
  • Can sharpen most serrations such as spyderco and benchmade. Can sharpen recurved blades with no problem.
  • If your blade is badly damaged, this system is useless for you.
  • You only have 2 angle options to set: 15 degrees or 20 degrees per side. I wish more.
Lansky LKDMD 4-Stone Deluxe Diamond Knife Sharpening Kit
  • Allows for "custom" sharpening of a given knife, beyond what other systems with limited sharpening angles or grits provide.
  • Stones are great, I get a perfect razor edge in just a few swipes!
  • I love the angle that you're able to hold with this system. It's almost a "set it and forget it" system. As long as you use the same slots each time and ensure that the rods are set correctly, you'll be able to produce a fine edge with very little work.
  • Does what it's supposed to and sharpens knives quickly. You can't ask for more. I purchased the Sapphire Polishing Hone separately to get the blade extra smooth. Otherwise, the finest diamond hone leaves the blade with a noticeable edge.
  • Sharpening many knives, especially those that are worn, larger, or need re-angled, can be a lot of work. Sore wrists and blisters can be expected if you have a whole set of knives to deal with.
  • At the lowest, flattest angle, the guide rod hits the rear screwhead and the hone hits the clamp at the ramp. I would buy a shorter screw.

What customers say about "Features"
Spyderco Tri-angle Sharpmaker 204MF Knife Sharpener
  • A relatively compact package for a sharpener, but it's way too big to fit in your pocket.
  • Compact-fits snugly and entirely inside stand so its great for travel.
  • I love the case holding everything. The new base is wider then what I was used to and thus feels sturdier. Also when attached the cap/handle gives more to hold on to.
  • With the optional ultra fine and diamond rods it can do most anything you'd need to maintain or resurrect a knife edge. The scissors feature is cool, too.
  • The only downside to me is the base/case. It seems a bit flimsy and cheap. It holds the stones fine for the actual sharpening, but I have had it open real easy just being stored. This is not enough for me to go below 5 stars though.
  • The quality of the system is fairly good. I do not like the plastic base though. The rods do move around in the slots and I can see that overtime there will be some wear and tear leading to a looser tolerance and in turn, more movement.
Lansky LKDMD 4-Stone Deluxe Diamond Knife Sharpening Kit
  • The whole kit has a small footprint and can store nicely.
  • Components allow for easy swap/replacement of parts.
  • Guide rods need some tweeking to get straight with stones, but once you get them there label them for each stone and you won't have to bend them again.
  • I'm also a big fan of the "compactness" of the product. All four hones, the guide rods, useless oil, screws for larger knives, and the universal base (purchased separately) can all fit into the case and transported easily.
  • The clamp - my old one from the 80s is machined aluminum, this new one looks and feels cheap, the jaws are not finished for a positive seating of the blade but a few minutes with a file will solve that problem.
  • I'm not a fan of the thumb screw on the back of the stones. They stick out so much that you're unable to use the whole stone's surface to sharpen. To fix this problem I went to the local big box home improvement store and bought a 3/8" 10-24 thread set screw to replace the thumb screw.
