Spyderco Knife Sharpener Tri-angle Sharpmaker Used to Sharpen Hunting Knives & Self Sharpening Knife by Using Ceramic Knife Sharpening Stone

I had researched that this sharpening system was one of the best. It's expensive but such an important part of maintaining your tools it's proven to be a worthwhile investment. It's very easy to use and I instantly saw the results.Included are two different grit of stones; a grey, coarse stone and a white, fine grit stone. The grey one is capable of producing a good working edge, sharp enough to slice through paper with no issues. Moving on to the white stones will then produce a razor sharp edge, capable of shaving hairs or even shaving paper.I first tested this on two folding knives which had an ok edge to start with, just not particularly sharp. They were razor sharp within 5 minutes just by using the white stones. I then tried some kitchen knives, one of which was just plain dull. Working through the steps outlined in the instruction booklet (greater detail provided in the accompanying DVD) I was able to bring them back to a razor sharp edge.So far it has handled everything I've tried with it (knives, nail clippers, scissors, picks...) and given great results. It's super easy to use since you only need to make sure your blade remains vertical as you draw it down the stone. No water or oil is required either.

This did an excellent job on a range of knives and other bladed items.The manufacturers have opinions and convey you them, which is excellent; for example, they recommend cutting angles and say why.The devices comes with two "medium" ceramic stones and two "fine" ones. All these stones are triangular in profile. The main advantage over "plain" stones is that the device keeps the grinding angle consistent -- not by clamping the knife, like some ultra-expensive devices, but by having you keep it vertical (which is fairly easy), with the stones angled, rather than you holding the knife at an angle to a horizonal stone. The basic sharpening sequence advised is 20 strokes per side for (a) medium, using the edge/corner; (b) medium, using the flat; (c) fine, using the corner; and (d) fine, using the flat. If you have knives that have been particularly abused (e.g. put through a dodgy wheel-based sharpening device) then I found it helpful to start with 20-40 strokes per side with a diamond "stone" (Spyderco SPY-204D Tri-Angle Diamond Sharpener, sold separately) to get the edge back to the right shape. (Possibly the medium stone would have done the job given a lot of patience, but this was definitely helpful.)The booklet and DVD (or YouTube video) also show you how to sharpen things other than "plain" knives -- such as serrated blades, scissors, potato peelers, and so on.The whole thing is definitely pricier than cheap wheel-based or scraping sharpeners, but there are much more expensive things out there too. Good value, I think.

After reading about lots of different techniques and products for sharpening knives I finally settled on this after some glowing reviews from around the internet and I must admit I am very very happy with this product.The first knife I sharpened was a cheap, yet brilliant, Victorinox pairing knife which had been slowly getting duller and duller for the past few months. Within 10 minutes it was razor sharp again and as good as new. With the included brass rods I never worried about cutting myself either.The instructions come in DVD form and in a manual and are very easy to follow but I would definitely invest a few minutes paying close attention to them as I think it would be as easy to ruin a knife as it is to sharpen it. In a nutshell however you start with the brown stones in the 40 degree holes and run the blade, held perpendicular, down the edge of the stones 40 times (20 each side in turn). You then do the same again on the flat of the brown stones before moving on and repeating the same process on the white stones. The one tip that I cannot stress enough is to not let the tip of the knife run off the stones as this will quickly round the tip and you will have a time re-profiling again.After building up a bit of confidence with the sharpening system I sharpened a few of my more expensive pocket knives and the results were just as impressive. All in all I would recommend this to anyone who wants to keep a few kitchen knives sharp to anyone with a keener interest in knives.

So I needed a knife sharpener that worked properly; one that sharpens my the SV30 steel blade on my new Leatherman Charge TTi (I had originally intended to get a much cheaper model...). Did the usual internet research and this came up again and again. A knife sharpener; that retails at about £100; even at this Amazon price, is still ludicrously expensive. No matter, it's the best and being a modern man, only the best will do - after all I can't possibly suffer the crushing embarrassment of a less-than-razor-sharp pair of nail clippers.So a few days later (slightly vague ordering process, no tracking but arrived sooner than expected) it arrived. Open the small A4 sized package and I seem to have paid £70 for a small plastic box containing a few sticks. Oooookay…So I stick on the DVD; ignore the cheesy advertorial style and a rather affable chap who clearly lives for sharpness soon charms you into sharpening anything from your best knife to your dogs claws; with consummate ease.I can now do the "shave off my arm hair" trick with anything remotely resembling a blade - even my keys.So yes it's a LOT of money but this is what you pay for owning the Top Gun elite of blade sharpeners that even a child (not recommended) could use.
