Or, use a small piece of duct tape between the blade and the holder.

Make and use a strop when you think the blade is sharp.
The strop will finish the job and the blade will be scary sharp.

Make a strop out of a 2" x 12" piece of scrap leather or old belt by rubbing some polishing compound into a wet leather.

I'd rather die in a BAD gunfight than a GOOD nursing home.
