Carving tools - hamlertools
This curved knife was modified to convert the tool into a saw. This is an old watchmakers trick, they would put teeth on a double edge razor to convert the sharp blade edge into a saw. Once a wood handle was applied to the blade they would use it to saw a small kerf on a shaft for terminating the mainspring. This tool can be used for scoring or pre scoring the wood where it would traditionally be done with an exact o knife or layout knife. The advantage is you are now sawing the wood thus reducing the probability of the blade from following the wood grain.
The control with this miniature veneer saw is so good you will seldom need a straight edge .
To form the teeth in most any sharp knife edge blade you install the blade in a machine vise with the edge up. Next lay one flat of a three sided small triangle file on one edge and slightly tap the file. This will swedge teeth into the blade, rotate the file and retapp until you cover the required length. Last swipe both sides of the blade with a hard Arkansas stone to remove metal that was forced out of the saw gullies.
