Leather Craft Isometric Divider Ruler | Equal Spacing Tool

Precision Equal Spacing for Leather Crafting

Whether you're crafting belts, watch straps, shoulder bags, or waistbands, achieving perfectly even spacing is one of the most challenging — and most important — aspects of leatherwork. This Stainless Steel Isometric Divider Ruler takes the guesswork out of marking equal divisions on any leather piece, giving you consistent, professional results every time.

Available in three sizes (S, M, L), this compact marking tool fans open to set your desired spacing, then locks in place (M and L models) so every mark lands exactly where it should. Ideal for installing decorative nails, spacing eyelets, punching stitch lines, and marking horizontal seams on belts and straps.
