Gee, you joined in 2010 but this is your first post?
Anywho ...
The Ontario SP10 Marine Raider has a stick tang. You'll probably have to cut it off. You might try drilling out the lanyard tube and see if the handle can be pulled off.
Either way, you'll need to carve a new handle out of wood or build up a stacked leather/wood/whatever handle.
If you decide to do it, be sure to post pics. We'd luv to see how you did it. Have fun.
