Actually the thinner the steel the more danger of ruining the temper so you have to be VERY careful. A thin edge can get red hot almost instantly and totally ruin the temper. I usually thin my edges on the Lansky because it will never do that and so long as you keep the clamp in the same place you will have a perfectly straight edge. It does take a long time although the HC is not as bad. I did my YKLE though and it took a lot of hours.

I much prefer knives like the HC to folders. With a good sheath with a clip you can wear it the same as a folder in your front pocket and it is faster to bring into action.
