HIDDEN LINE TRANSFER TOOL

I posted this because of GARY L ,this site needs more posts and here is a tool that I have used over the years building curved stairs and marking veneer .

Just a little tool I made from scrap to transfer joint lines onto veneer with a marking knife .
The joint lines on edge of this table base need to be transferred to the veneer but one the strip of veneer is placed on top of the edge it is hidden since the strip needs to be oversize in width.
The solution is to fasten a piece of veneer on the joint line and place the veneer to be cut on top of it ,place the transfer tool along the bottom veneer strip and mark the line .
Yes this is not a normal marking knife but I made this work with a blade that has a single bevel with one flat side which I run along the tool edge .
This is a tool which I have used for many years transferring line from a curved stair layout to mark lines onto the oversize tread blanks , it eliminates squaring the line from the pattern up to the top of the tread .
Versions of this should be handy in many other situations .
