Midway has a whopping 2% off of list price on the Dem Bart starter checkering kits, $44.99. That’s the best discount we’ve found! I’m listing it anyway as a caveat: these checkering tools are reasonably priced at retail. I made the mistake of thinking I was getting a good buy at the flea market last week, buying a single tool for $10.00. Turns out I paid close to retail! I couldn’t believe that a specialty tool was so cheap.
In any case the starter kit comes with three handles and six tips that interchange in the spacing ordered (in TPI) as well as a diamond spacing gauge. They are (obviously) used to do checkering on gunstocks, pistol grips and any other wood that needs a grippy surface. There isn’t a lot out there on the web, but there are many books that will show you what ultimately is a skill that requires a lot of practice.
