Review: Now that I know this can be re-sharpened, I think I will use it a lot more. - My favorite blade! Just one problem, they are $$$. Guess what? It is possible to re-sharpen these to (better than original) razor sharp! I used only the (older ver. finer than newer ver.) pink very fine stone from a Lansky sharpener, with the 17° angle. It is tricky to get the blade clamped so that it sticks out enough that the stone will not hit the clamp (may need to use shims to secure in Lansky's holder). But very little force is required to sharpen. In fact, as little as possible (to avoid bending the blade and messing up the angle). One you get it in position, and clamp it real tight, a total of about 10-20 very light strokes w/ oil alternating each side and making sure to cover the whole edge will get it sharp enough to make hairs from your arm simply pop off and flee for their lives. I did this to a blade that had been used to scrape glue off the rough surface of broken ceramic, so it was severely dulled. But it came back to good as or better than new! Now that I know this can be re-sharpened, I think I will use it a lot more.
Review: Great blades - I like these a lot more than the straight ones. The curve allows you to cut more smoothly as you glide through the edge. Really good blades!
