I have been palm stropping all sorts of blades for about 15 years or more.
I don't see why straights are more difficult, dangerous to do than any other blade.
I have stropped axes, khukri's, shun blades, what ever and when ever. And never once had a cut from a cleanly honed blade, just don't do it if you have nicks in the blade, as an axe might in the field after a day of chopping.
