I was making a project in olive wood. It was so hard that my knife line was hard to see. My veneer saw was laying in the tool well. It is the old fashion one with the sawtooth edge on two sides and a flat edge on the other. You just flip it over to place the flat side against your straight edge and you pull across and now you have a very distinctive knife wall. If you saw is dull, you can sharpen the beveled edge just like a knife. Tag Frid has a picuture of him doing just that. I still use my Stanley pocket knife like Paul’s, but I have found the veneer saw to make a really nice line, especially for dadoes.
