Our flat wire ribbon inlay has been updated to a more correct width according to standards of application by some of today’s master craftsmen. It is really not hard to do, but takes practice and good technique. The Art of Building the Pennsylvania Longrifle has a good section on installation. Our flat wire comes in 36” lengths in brass and German Silver .005, .008 and .014 thick. Sterling silver comes in .010 thickness, only in 36” length as well. The height of the wire averages .050 to .055.
