Real Gear Reviews

The cheap option is usually fine. When it isn't, this site says so. Reviews include real cost-of-ownership math, not "5 stars on Amazon" reasoning.

Why this page exists

Leatherwork content online is split between artisans selling courses and hobbyists oversharing on Reddit. This site is run by a person making belts and small goods at a kitchen table.

The SPI math accounts for what hands can actually do at a kitchen table, not what an industrial machine produces. The $40 awl is fine for most projects; the calculators help you decide when the $200 set is justified.

Plain note about money. Some links in the reviews and calculator results go to product pages on eBay with an affiliate tag. If you buy through one, the commission pays for the site. Your price doesn't change. The cheap option is usually fine; when the expensive option is worth it, this site will explain exactly why.
