Start with a useful profile
The catalogue includes common Japanese kitchen knife families in practical starting sizes. Every profile is adjustable, and a blank drawing mode is available when a preset is not the right place to begin.
Keep control of your files
Designing, printing and exporting do not require an account. Download JSON to keep an editable local copy. An optional free account adds cloud saves and frozen, revocable share links.
Verify before fabrication
The tool provides geometry and layout assistance, not engineering or manufacturing approval. Check every dimension and curve, verify every actual size print, and use appropriate workshop skill and safety practices.
Built as a durable browser tool
The editor uses plain TypeScript, DOM, SVG and a dependency light PDF path. A separate offline build keeps designing, local files, printing and export available without a hosted service.
