Blades developing a Hook to them

[Sam]

Hi All,

I have noticed that a couple of my straight blades (wharncliffe style) have developed a slight hook along the sharp edge to the tip after a lot of use and a lot of stropping. The knives still hold and take a good edge in this shape but, I have since taken them down straight again and rehoned and stropped. I was wondering if anyone knew what causes this hooking so that I may be able to prevent it? Functionally they are fine, but I like to keep them straight and maybe it means I am doing something incorrectly.

Sam,
That is perfectly common with all straight edge knives.
The effect comes from removing more metal from the center of the cutting edge when sharpening and/or stropping. It is a slow process and not one to lose sleep over.

While it doesn't have a noticable effect on the blade, it does look a little funny.

It can be removed, but requires removing more metal from both ends of the blade to obtain a true straight edge.

If you look closely at my knife, you will see the beginnings of a hook.
I returned it to a straight edge after this photo was taken.

Thanks Rick - That's what I figured, but couldn't understand how I was removing more metal while sharpening and stropping. When I re-flatten the blades, I end up shortening them a little too cause the tip gets to be too pointed and fine.

Sam,
When your knife blade keeps developing a hook and getting shorter, that means you are a dedicated carver.

It only happens when you do some serious carving

I've noticed the same thing happening with several of my knives. My favorite, most used one has really taken on the hook. I wasn't aware that this could be corrected, so just let it go.

Rick, do you think this one is beyond help, or can you correct the hook if I send it to you?

Al,
I'm afraid you hit a snag with that one.

I doano Al, about hitting a "snag", but it sure looks like a "gaffe" on your part. Head Bange

Cheers.

Old_Gord,
I see you got caught up in this discussion. If you're not careful, you could really get hooked.

You have to watch Al, his wit is as sharp as his tools; he will sometimes reel you in and before you know it, he is playing you for a sucker.

I am afraid I must cut-the-line on this one before I need my waders.
