Product Description

Product Description

The Tri-Angle sharpmaker set includes: toe medium-grit triangle stones (brown) two fine grit (white) an ABS plastic base with lid two brass safety rods an instructional booklet and an instructional DVD.ATTRIBUTES Includes: One Pair Medium Grit Triangle Stones One Pair Fine Grit Triangle Stones Abs Plastic Base Pair Of Brass Safety Rods Special Features: Instructional DVD Storage: Base with Snap Lid


The Tri-Angle Sharpmaker (204MF) includes two sets of high alumina ceramic stones, a pair of medium-grit 7 by .5 inch stones for aggressive sharpening and a set of fine white 7 by .5 inch stones for professional grade finishing. The stones are triangular for sharpening plainedges on the flat sides and SpyderEdges (serrations) on the corners. A furrow running the length of each stone lets you sharpen pointed items like fishhooks, darts, and awls.

Included is a set of brass safety rods to protecting your hands while sharpening. All components snap into the self-contained ABS plastic base and lid and are ready to travel with you. Die-cut into the base are keyed slots and holes fitted for the stones, which accurately set the stone's sharpening angle at for knives and a scissor setting.

Turn the base over, a channel lets you lay two stones side-by-side (flat-side up) for use as a benchstone. The lid snaps halfway over the base creating a handhold for stability while you're sharpening. Included is a set of brass safety rods to protect the users hands while sharpening. Ceramic stones, like glass, will break if dropped, so Spyderco advises you to handle carefully. Use them dry, without oil, water or lubricants. To clean, scrub stones with a plastic scouring pad and powered abrasive cleaner, let air-dry. The sharpening system comes with instruction book and DVD and is autoclave safe.

Chances are you've heard it said, "a sharp knife is safer than a dull one." Spyderco believes this quote originated from first hand experience and find it to be true. The Sharpmaker was Spyderco's first product, which the company made and sold before getting into the knife business.

I have been sharpening knives on flat stones by hand for many years. I just got a Spyderco Sharpmaker, and it's the best contraption I have ever used.

The stones are good quality. Similar cheaper brands have lumps on otherwise perfect stones, making them almost useless. Both the coarse and fine stones leave a relatively fine edge considering how well they remove metal.

The triangular shape of the stones makes them work very well for regular knives and serrated knives as well.

It comes with an instruction book that tells you exactly what to do. If you follow the instructions, you will get a very sharp edge. The only skill involved is holding the blade up and down, and that isn't hard at all.

The price looks high, but you get a total of 4 long stones (two fine, two medium) of good quality. It is well worth the price to be able to keep your knives sharp on your own instead of paying someone to do it, which adds up fast.

I don't recommend sharpening systems that involve clamping a guide system to the blade because they tend to slip and/or scratch the blade, are annoying to use for quick touch-ups, and don't actually maintain a good angle along the whole blade due to the mechanics involved.

Boy! If I sound excited about this item, you bet your butt it's true! This marvelous tool belongs in EVERY kitchen, ASAP!

I am 59, almost 60, and have used knives all my life, both outside, and inside, and especially in the kitchen. One thing I was never taught by my dad (died when I was 10) and also was never able to "master" in these subsequent years, was how to sharpen a knife! Trust me, I can take a dull knife and make it duller!

Then, Zam! I'm at a local (big, well-known, name) shop here two weeks ago, and they are giving a knife sharpening seminar in the hunting & archery department, so, naturally, I trecked upstairs to check it out.

Well, the guy doing the demonstration showed us 3 things, a flat oilstone system, a hydrastone system, and this little baby. He thoroughly went through all three systems with us, carefully explaining their workings, and what they are best for.

Hydrastone and oilstone are for outdoor/sporting/pocket knives, where you want and need a very fine edge to the blade, and always polishing at the end with a leather strop and jeweler's polish.

But, for KITCHEN, the single best item is this system from Spyderco. I saw it work, I even tried it myself, and can do it! And, if I can do it, you can, too! Trust me! I purchased this ON THE SPOT, and it was NOT an impulse purchase, either!

Every knife in my block, and in my utility drawer is now razor sharp, able to slice down a piece of adding machine tape (paper). What a truly GREAT feeling to pick up ANY knife and be able to cut with it! I'm in heaven! Another tip...when finished with ANY knife, wash and rinse in hot soapy water and wipe dry immediately....

Dear prospective buyers,

I've read all of the negative reviews on this product, as well as many positive, and have come to the conclusion (with the additional experience of my own use) that if this isn't working for you the error is the your own.

I've been able to get shave sharp edges on every blade I've passed on this sharpener and have had no similar results from any other sharpening device. Please be aware, however, that I have spent innumerable passes on some knives that do not have an edge close to 40 degrees, have thick blades, and are composed of hard steel (Chris Reeve Mark VI in particular, A2 tool steel at 55-57 rockwell hardness). Your results will definitely differ based on these factors, your technique, and tenacity. If you have a friend with a grinder and a steady hand, you can have him/her back bevel the blade to around 30 degrees, which will make the initial 40 degree edge setting process much easier. Basically, as long as the back bevel is less than 40, honing in the edge will be a snap.

If you keep the stones cleansed of steel it will help immensely. This may require frequent Ajax scrub downs, but it's worth the extra effort in the end. I must admit that the coarse stones are beginning to wear on the triangle points of my sharpener, but I've had the thing for at least 3 years and use it all the time. My guess with unsuccsessful users is that they don't stick with the coarse stone long enough to get the edge to 40 degrees.

Some additional advice: do not go past the tip of the blade when using the triangle point of the stones. It rounds the point and (because I made this mistake I know) makes reshaping the point very time consuming and difficult.

I've had one for two months and have mixed feelings.

I've never been able to manage the accuracy required to sharpen anything freehand so I needed an aid to help me out. The Sharpmaker is really good at assisting with maintaining the two knife angles. It does take a little attention to make sure that you hold a blade vertical through the entire stroke, but it takes a lot less that holding a blade elevated off a flat stone. In that respect this product works really well.

However, it turns out I have a house full of neglected knives, scissors, etc. Not only are they not sharp, many are actually damaged with nicks out of the blade edge. In order to sharpen these edges, you need to remove quite a bit of material. The medium stones supplied with the Sharpmaker are fine for touching up a mildly dull blade, but they just aren't up to the task of removing lots of material, at least not quickly.

Further, it seems that most of the edges I have to sharpen aren't anywhere near preset angles that the Sharpmaker is designed to sharpen. I have some knives at just over 40 degrees. I have some kitchen knives that are chisel ground to around 12 degrees on one side (a little steeper than the 15-degree angle that the 30-degree edge is designed for). Of my 5 pairs of scissors (different brands), none of them is angle to match the 12.5 degree slot in the base of the shapener. For scissors, it isn't too hard to hold the cutting face flat to a stone since most are pretty broad. But for knives, if they don't match the 30 or 40 degree angles, you have two choices if you don't want to revert to free hand sharpening.

1) For edges that are a tiny bit steeper than 30 or 40 degrees
a) put a micro-bevel primary edge on them.
