Craftool® Hand Border Tool

Took me a few tries to get the hang of it, but once I did, my swivel knife follows the guide ridge perfectly for those straight border lines. Saves so much time compared to measuring and eyeballing each section.

Finally, my borders come out straight every time without constant measuring. The groove that guides the swivel knife is snug enough that I don't slip off mid-line, which used to drive me crazy.

I was nervous about keeping my swivel knife straight along the edge, but this guide tool makes it incredibly easy to lock into a consistent line. The wheel runs smoothly and the spacing on my test piece came out perfectly uniform.
