Tamiya Craft Tool Series No.98 Modeler's Knife PRO 74098
Tamiya Craft Tool Series No.98 Modeler's Knife PRO 74098, a precision knife designed specifically for plastic model work.
A hobby knife is the scale modeler's scalpel, used for trimming nubs, cleaning mold lines, cutting decals and masking tape, and shaving away flash. Most builds touch a knife dozens of times, so a comfortable, secure tool directly affects the quality of your work. The classic No. 11 blade handles most jobs, but curved and chisel blades open up scraping and plank-cutting tasks. When choosing, look at handle grip and weight, how firmly the collet locks the blade, blade change convenience and availability, and whether the set includes multiple blade profiles. This guide covers hobby knives and blade systems that stay sharp, feel precise, and keep your fingers out of trouble.
