Most of my carving tools are flexcut, primarily because that's whats available in my price range. Also I like the fact that all I have to do is hone them a little with their gold compound and I'm good to go. I'm deathly afraid if I use sandpaper or a stone on them I will ruin an expensive chisels. I primarily use a reciprocating handpiece so I can carve woods of varying hardness. Now I would like to use some mallet tools like Pfeil or Auriou and they are upwards of $50US apiece(Ouch) So..

My question: Can I keep these sharp with just honing or will I have to use stones and or sandpaper?

Thanks,
Paul
