Knives and Blades – Precision Cutting Tools for Modelers

Sharp tools make clean models. Our Knives and Blades collection brings together the cutters, saws, engravers, scrapers, and replacement blades you reach for on every project. From trimming sprues and opening panel lines to scraping 3D-print layer lines and shaping putty, the right edge saves time and leaves a safer, cleaner finish. Whether you build aircraft, armor, cars, or miniatures, Knives and Blades help you work faster and with more control.

What’s in this collection

Find an extensive selection for every task and budget. AMMO by MIG offers standard and mini blade sets (straight, curved, chisel), precision pen knives, protective blade handles, and silicone applicators for putty work. GSI Creos / Mr. Hobby adds design knives, modeling file blades, and fine micro-saws for delicate plastics. Tamiya’s Fine Craft Saws and Fine Engraving Blades deliver clean rescribes and stress-free resin gate removal. Excel supplies the classics—#11 and specialty blades, ergonomic handles, and generous replacement packs. You’ll also find Monument Hobbies retractable hobby cutters, NO-NAME Smart Scraper for 3D prints, snap-off light-duty blades, cemented-carbide engravers from 0.3–1.5 mm, and plenty of refills so your bench never runs out of sharp edges.

Benefits, tips, and best practices

A matched tool makes a visible difference. Use a fresh #11 for thin styrene; switch to a chisel blade to shave seams flat without digging. Micro-saws shine where scoring and snapping could stress brittle parts or resin. When rescribing panel lines, guide the blade with masking/DYMO tape, take multiple light passes, and clear dust often to keep lines crisp. For decals and masking film, score lightly rather than pushing through paint to avoid ridges. On resin, cut gate stubs with a saw first, then refine with a curved blade. For 3D-printed parts, scrape layer lines with a protected handle or smart scraper before sanding—faster, flatter, safer. Replace blades frequently: the moment a cut needs force, you risk slips and ragged edges.

Safety & maintenance

Always cut on a self-healing mat and pull the blade away from hands. Wear eye protection when sawing resin or using carbide engravers. Solvents and plastic dust dull edges—wipe tools after sessions, tighten screws on pen knives, and oil moving parts on retractable cutters. Carbide engravers last longer if you avoid twisting; let the tool follow the line. Store handles retracted or capped, and sort refills by size/shape for quick selection. With simple care, your Knives and Blades stay accurate, predictable, and ready for fine work.
