Klein Tools 44101 – Frequently Asked Questions

1) Will Klein Tools 44101 blades fit a utility knife from another brand?
Yes. The 44101 blades are a universal size that fits Klein utility knives and most other makes. They measure 2.438 inches (6.2 cm) long and 0.025 inch (0.6 mm) thick, which is the standard trapezoid utility blade dimension, so any knife taking a standard replacement blade will hold them.
2) Are these blades safe to use on live electrical work?
No. Klein states the 44101 blades must never be used on or near live electrical circuits. They are uninsulated steel blades. De-energize the circuit before cutting, and wear approved eye protection. If you need to work energized, you need an insulated tool, not a bare blade.
3) How many blades come in the Klein 44101 pack?
Five replacement utility knife blades per pack, part number 44101. Each is razor edged and reversible, so you get two cutting edges per blade, ten usable edges from the pack.
4) Can I snap the Klein 44101 blade to get a fresh edge like a snap-off knife?
No, these are not segmented snap blades. The 44101 is a one-piece heavy-duty razor-edge blade at 0.025 inch thick, and bending it can break it and cause injury. To refresh the edge, pull the blade and flip it end for end, since it is reversible.
5) What do these Klein blades get used for on an electrical job?
Stripping and scoring cable jacket, cutting NM sheathing, slitting insulation, opening cartons and trimming drywall or foam around boxes. They are heavy-duty razor edged, so they hold up to jacket work better than a thin craft blade, but the manufacturer is explicit that they are for cutting only, not prying or scraping.
6) How much does a pack of Klein 44101 utility blades weigh for MRO stocking?
The 5-pack weighs 0.8 oz (23 g). Small enough that facility stockrooms and service vans typically buy them several packs at a time rather than singly.
