Which Cutter Uses CTB-5 Blades?
The OLFA CTN-1 Carton Cutter. This is the direct-fit replacement blade — compact, powerful, and purpose-built for carton work.
CTB-5 vs LB 18mm Blades
CTB-5 blades are shaped for the CTN-1's compact carton cutter body and controlled-depth cutting; standard LB 18mm snap blades fit general utility knives. Use CTB-5 for CTN-1 handles.
How to Change CTB-5 Blades
Slide the CTN-1's blade release, remove the spent blade, insert a new CTB-5, and it's ready. When an edge dulls, snap off a segment with the handle's snapper for a fresh edge in seconds.
Price and Deal Value
Thirty edges for $5.99 means about 20 cents per fresh edge. Coupon BENCH10 takes 10% off, and orders over $45.00 ship free — stock the supply closet for less.
