A lot of boatbuilding seems to revolve around woodworking. Even if you’re inclined to a steel hull, most of the interior will still be wood. There are all kinds of resources for woodworking knowledge, both on the net and elsewhere. Despite being somewhat familiar with this field, I had never ran across the "Scary Sharp" method of tool sharpening. I guess since I tend more toward rough and read wood butchery instead of fine joinery, the fine arts of tool sharpening have passed me by.
Anyway, check it out… its a method of sharpening using sandpaper instead of the more common stones, etc.
