The problem: heat treat notes scattered everywhere

If you've been making blades for a while, you probably have heat treat notes in at least three places: a shop notebook, a half-broken Excel file, and your memory. That makes it hard to repeat what worked — and avoid what failed.

Lost and scattered notes

Shop notebooks get dirty, lost, or filled up. Spreadsheets live on an old laptop. When you need that one perfect 80CrV2 recipe from last year, you're flipping pages or digging through files.

Hard to log during real work

In the middle of forging, grinding, or tempering cycles, you don't have time to fuss with spreadsheets. So logs get postponed — and often never written at all.

No way to see patterns

You experiment with soak times, quench media and temper temps, but without structured logs, it's hard to see what consistently works for each steel — and what tends to crack or warp.

Risk of losing years of experience

If a notebook gets ruined or a hard drive dies, you lose more than notes. You lose years of heat treat experiments and hard-earned lessons.

BladesmithHub keeps your heat treats and builds under control

It's a digital logbook and build tracker designed specifically for bladesmiths and knifemakers — not a generic notes app.

A structured heat treat log

Log each heat treat with steel, steps, temps, timing, quench and results in seconds — on your phone or desktop.

Build sheets for each knife or tool

Tie multiple heat treat logs to a single build. See the full history of a knife, axe or tool in one place.

Searchable, filterable history

Filter your past logs by steel, result or date to quickly find "what worked last time" for a given steel.

Your data, safely stored and exportable

Keep your recipes backed up and export them any time as CSV/JSON. No more fear of losing years of notes.

How it works

Built around the way you actually work in the shop.

1

Choose your steel

Pick a steel from the built-in library or your own list. See your go-to heat treat notes for that steel at a glance.

2

Log the heat treat in seconds

Use a Quick Log to record temps, soak times, quench and temper steps while you work — or later from your notebook. No bloated forms, just the essentials.

3

Tie it to a build and repeat what works

Attach the log to a specific knife or tool, add results and notes. Next time you use that steel, filter your logs and reuse a proven recipe.

Designed for bladesmiths, not spreadsheets

BladesmithHub focuses on the pieces of your process that matter most for repeatable heat treats.

Quick heat treat logging

Create a new log with a few taps, on your phone, while the forge is still hot.

Steel library

Keep your most-used steels and their heat treat notes in one place. No more guessing or digging through PDFs.

Build sheets (projects)

Group logs, notes and results under each knife or tool you make.

Search & filters

Find logs by steel, result or date when you need to repeat a successful treatment.

Mobile-friendly, dark theme

Built to be used in the shop on a phone, not just at a desk.

Export your data

Download your logs as CSV/JSON for backup or further analysis.

Is BladesmithHub for you?

Serious hobbyist bladesmith

You make a handful of blades each month, experiment with different steels and heat treats, and want fewer surprises and more consistency.

Semi-pro or pro knifemaker

You sell knives to customers and care about repeatable quality and your reputation. You already track builds somehow — but you're tired of juggling notebooks and spreadsheets.

Apprentice / learner

You're learning from a master or on your own and want a structured way to capture what you're doing and how each blade turns out.
