Thread: 01 + bamboo convex

Very interesting look. Other than aesthetically speaking, would you say there are any advantages to a convex grind in comparison to a concave grind and if so, what would they be in your opinion?

Thanks.

I like this look however it brings up an interesting question. If this convex shape works well then why are razors shaped concave? I know I am not very knowledgeable on the shape of razors and why they are the way they are. But to me this is an interesting question. It sure would eliminate a ton of grinding. Hmmmmmmm let's think "out of the box" on this one.

Not the highest quality image I'm afraid - the conditions are a bit adverse here at the moment.

The Bamboo scales ARE very light. For me this is a plus because I prefer to derive the balance from the blade rather than the scales which are sort of "just hanging there" between my second and third fingers. Naturally, this is a matter of personal preference. I'm sure there are others who would prefer a much heavier set of scales.

I think the real added benefit of true concave grinds kicks in when hand sharpening & honing is involved - especially in the hands of beginners or folks who simply don't do a lot of sharpening and honing. The geometry of a true-hollow will aid in keeping a constant angle to the plane almost intuitively - while a convex will require very steady and deliberate angle management.

I dont think the particular geometry of the grind has anything to do with the sharpness of the blade. Hair splitting sharp is hair splitting sharp - isn't it?

Hi Alchemist,

Nice blade indeed. Is it a zero ground blade? By that I mean is it one continuous convex all the way to the cutting edge, or is it a convex grind with a v-grind microbevel?

Convex grinds, zero grinds and convex edges are what I do all the time on hunting knives and big choppers, and I can tell you that it takes some skill to pull off a wicked sharp zero grind blade on a big knife let alone something like a straight razor. I applaud you for jumping out there and being different. I love it!

I have not yet attempted it on a straight razor, but you can bet I will.

Nice job Alchemist!

I would say that it has a V type micro bevel, because it was honed on flat stones and then stropped on a wood mounted leather (as opposed to a hanging strop). I think if I strop it on a hanging strop later on it will, over time, become a zero.

Very nice work, especially the grinding.
