Leatherworking tools and honest reviews. For hobbyists building belts, wallets, and small bags who are past the first cheap-kit phase.
Most leatherworking content online is YouTube hours of "follow along" without much why-behind-it. The math hides in the comments sections. SPI choice, edge finishing chemistry, thread tex sizing — all of it is googleable but scattered.
These tools bring it together. Stitching pattern math by leather thickness. Belt sizing math. Tool recommendations that aren't all from Tandy.

Plain note about money: Some product links are affiliate (eBay Partner Network). Small commission on purchases. Doesn't change your price. The recommendations come from actual project time. Some excellent tools are made in Japan by people without affiliate programs; I name them anyway.
