What customers say about "Key Specs"
Edge Pro Apex 4 Knife Sharpening System
  • Once you get the hang of the sharpener, it works great. I used an digital angle gauge (I'm a woodworker) to set for type of knife.
  • Pretty much every knife I owned needed to be re angled from years of hand sharpening so the 120 got a ton of use.
  • Amazing knife sharpening system ! I'm a working chef and since purchasing this kit two months ago I keep my knives sharper than ever ! Highly recommend!
  • Undoubtedly the best knife sharpening system I have ever owned. I don't know about how well this would compare against Kershaw's Wicked Edge, but I am highly satisfied!
  • The knife sharpener is great. With a little practice the process becomes quick and easy and you can get razor sharp knives in no time.
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"
Edge Pro Apex 4 Knife Sharpening System
  • When going from one stone to another, the variance can change the angle and create either a lot more work or an inconsistent edge.
  • This kit lets you do all of the stone sharpening and keeps the angle the same and really does an outstanding job.
  • The key to a good edge is to have a flat bevel, the correct bevel angle, and micro-serrations perpendicular to the edge.
  • The sharpener will get your knives razor sharp and you can maintain factory angles quite easily.
  • The reach of the tool is limited, so you'll have to move knives with long blades (more than about 6") from side to side to get to all of the blade. This makes it a little more difficult to hold the angle consistent.
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"
Edge Pro Apex 4 Knife Sharpening System
  • This was researched by my daughter who concluded this was the best value with the features she was looking for. She loves it!
  • The Edge-Pro can be quickly adjusted to accommodate blades of any size and shape, from heavy tactical blades to thin pen knives and everything in between.
  • When you switch to your next plate, use it as a feeler gauge, BUT move only the upper, original Edge Pro adjustment, instead of the collar. This will compensate for the difference in thicknesses and maintain your desired angle.
  • The stones last long as well. I sharpen professionally and this portable sharpener is my go to for all jobs requiring the utmost in sharpening precision.
  • It is a great design. The stones cut well and clean easily.
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.
