Every blade has a number

Temperline tracks what every build really costs — labour, materials, consumables, overhead — and runs your pipeline from enquiry to shipped. Built by a knifemaker.

We'll invite you when a spot opens. Cost one real build and it's yours for life — no card, no spam.

The maker's math

The most expensive material in your knife is you — and you're giving it away.

What it does

01 / PIPELINE

The temper-line pipeline

Every build moves along one line — enquiry, deposit, steel, grind, heat treat, handle, finish, shipped. See every knife in your shop at a glance, and what each stage is costing you.

02 / TRUE COST

The costs everyone forgets

Belts, epoxy, propane, kiln hours, the offcut bin. Temperline counts consumables and overhead into every build, so the number you quote is the number it actually costs.

03 / GOODWILL

A ledger for gifts & barter

The knife for your brother-in-law. The trade for a set of scales. Gifts and barter get logged at true cost, so goodwill stays generous — and visible — instead of invisible loss.
