Klein Tools 44100 – Frequently Asked Questions

1) Does the Klein 44100 utility knife take standard replacement blades, or only Klein blades?
It accepts most standard utility blades, so the common trapezoid blades already in your truck stock will fit. The blades are double-ended and reversible, which gets you four cutting edges out of a single blade before you throw it away. Three steel blades come with the knife, stored inside the handle.
2) Is the Klein 44100 safe to use on live electrical work?
No. The 44100 carries an explicit warning never to use it on or near live electrical circuits, and approved eye protection should be worn when cutting. It is a general-purpose cutting tool for an electrician's bag, not an insulated tool. If you need to cut on or around energized conductors, you want a properly rated insulated tool instead.
3) Will the Klein 44100 knife fit in a pouch or clip onto a tool belt?
The knife closes down to 6 inches (152.4 mm) and extends to 6.625 inches (168.3 mm) with the blade out, and it weighs 3.5 oz (99 g). The blade retracts fully for carrying, so it drops into a pouch safely. There is no belt clip on the knife itself; Klein sells knife holders under Cat. Nos. 5185 and 5248 if you want it to ride on the belt.
4) How many cutting depths does the Klein 44100 retractable utility knife have?
Three. A top button slides the blade to any of three cutting positions, so you can run it shallow for scoring Romex jacket or cardboard and drop it out full depth for thicker material. It also retracts fully so nothing is exposed in the pouch.
5) Do I need to buy spare blades with the Klein 44100, or does it come with them?
Three steel blades ship with the knife and store inside the handle, so you have replacements on you without a separate box. Since each blade is double-ended and reversible, those three carry you a long way. When you do restock, standard utility blades work.
6) Is the Klein 44100 utility knife heavy enough to be a nuisance in a pouch all day?
At 3.5 oz (99 g) it is not. The handle is aluminum rather than steel, shaped for grip, which is where the light weight comes from. For a maintenance tech or electrician carrying a full pouch, it is one of the lighter things in it.
7) What is the exact part number for the Klein retractable utility knife with blade storage?
Klein Tools 44100. That is the manufacturer part number to order against, and it is the retractable-blade model with three blades stored in the aluminum handle. Matching knife holders are Cat. Nos. 5185 and 5248.
