i was thinking about how i had been cutting my feathers and how it wasnt clean enough. so i went to the homedepot bought one rack of cedar shims and one pac of blades for a insulation knife. i drew the shape i wanted on a shim and began digging a narow groove untill i passed throught the shim. i inserted the razor, they bend really well, and epoxyed it in place. second i cut a shim the exact same shape as the frether so i put the small piece of shim on top of the feather flush at the quill set the razor over the uper edge and push.
