Spyderco 400 Square Ceramic Sharpening Files for Sharpening Small Detailed Tools

There isn't much to say here. It's a small, quality ultra fine sharpening stone. It'll last for ages if you take care of it. It has worked perfectly to polish metal parts and for trigger components in things that go bang. It's small, but does exactly what I need it to.

Very decent set of 1/4 inch ish size stones , they put a real nice polish finish on a small stainless steel job that I did . Nice set , nice leather pouch , good quality . I would buy again .

I am always afraid I am going to break these when I use them but they are pretty tough and I doubt I could snap them without trying hard to do so and a swipe or two from a Mr clean eraser removes all signs of use no matter what kinda metal they were used on. And not all ceramic sticks are the same quality, and these are super high quality and work quickly.

I purchased this slip stone to remove burs from the inside of my V gouges, which it does well. Then I decided to try it on my knives whose edges had rounded after much stropping. WOW what shock. This stone quickly removing the round and left a finely polished edge. After 5 strokes on each side of green compound my knives were amazingly sharp. I feel this improvement in sharpening was also due to how I sharpened the knife. In one hand I held the knife, I layer the rounded portion of the stone perpendicular to the blade then lifted it just a few degrees. Then I basically wiped the stone from the front to the back of the blade in each side maybe 10-12 times. The stone cut the steel with little pressure and left an almost polished edge that was extremely sharp which stropping improved even more. I can say that when I wear this stone down I will get another

Cute little pouch! The file set has several different shapes which helps with hard to reach areas. I wish there was a variety in the grit. The files are all the same grit (very fine). I've used them quite a bit and they do hold up well - none have broken so far. Good for deburring rough edges - although sand paper works almost as well at a cheaper cost.

I'm a tool & die maker, so I work with hardened tool steel up to 62 .. These are great for deburring tooling I've made that only require a small break-edge. They keep their shape and leave a great finish. The leather case is a bonus.

The ceramic rod does the job. It’s the perfect size to remove burrs inside V and curved wood carving tools. It’s small but very high quality ceramic grit capable of both tight curves or large chisel edges. It’s a must to maintain sharp tools. The price to quality ratio is fair indeed.

Great set of stones for working metals. The different shapes fit most needs you'll have. They clean up fairly easily.

Well made worth's the price

great quality. Recommend.

Zero issues.

Delivered as promised,
