Shape and editing
The straight facet gives the front a clear reverse tanto form. You can adjust facet length, spine height, edge rise and curvature independently while keeping an exact blade length and printable scale.
The base template is fully adjustable. Type exact measurements, drag the profile controls, set tang dimensions, add holes and marks, or convert the result into an editable node outline.
Choose a starting size
The 180 mm profile is compact and direct. The 210 mm profile provides more cutting length while keeping the same K tip construction. Both can be reshaped before printing or export.
Every output should be checked before fabrication. Printer settings can change scale, so print at 100 percent and measure the calibration ruler on the finished sheet.
Files for the next step
Use PDF for a prepared print file, drawing SVG for the complete annotated profile, cut line SVG for a clean outline, or DXF for compatible CAD and cutting software. You can also save the editable design as JSON.
