Description
The Kydex Holster Crafting Guide: Field Manual 01
A complete, step-by-step manual for building safe, consistent Kydex holsters, from your first sheet to your first sale. Written by the shop that made Kobra holsters, and rebuilt for 2026 with every forming number traced to the material maker's own technical data.
Revision 3.0, October 2026. Completely rewritten, corrected and independently audited. Forming temperatures, cooling rules and drill sizes now come from Sekisui KYDEX technical briefs and data sheets, not forum rules of thumb.
Who it is for
- New makers who want to get it right the first time
- Working makers who want consistent retention and fewer scrapped shells
- Anyone planning to sell holsters and wanting a real quality standard
What is inside
- Safety first: fume and dust hazards, ventilation that does not ruin your forming, and firearm rules for the bench
- Materials: KYDEX vs. Boltaron vs. Holstex, thickness selection and what the published data actually says
- Forming that works: temperature bands by thickness, the four stages of heat readiness, oven and heat-gun methods, and a validated cooling time
- Molds and templates: blocking a mold, laying out a fold template, and a 10-step first build
- Optics, lights and compensators: fit records and the rule that heat never touches working electronics
- Hardware: Chicago screw and eyelet sizing, correct drill sizes and safe adjustment limits
- Retention and QC: on-body and off-body tests and a 39-point final quality checklist
- Troubleshooting: causes and fixes for poor detail, warping, blisters, tears and loose hardware
- Business basics: pricing formula, insurance, payment processing and marketplace rules
- Appendices: supplier list, quick-reference tables, sources and a customer care sheet template
The details
- 53 pages, 17 chapters and 4 appendices
- 6 technical figures and 28 reference tables
- Instant PDF download, US Letter, print-ready, with linked contents and clickable sources.
