Klein Tools 44213 – Frequently Asked Questions

1) Will a tanto blade work for stripping cable jacket and skinning wire?
The tanto grind on the Klein 44213 is built around a reinforced point, so it excels at piercing a cable jacket to start a cut and at slicing through outer sheathing. Klein lists cable jacket removal, wire prep and insulation work among its uses. What a tanto does not give you is a continuous curved belly, so for long sweeping slices some electricians still prefer a drop point or a dedicated hawkbill cable skinner. For puncture-and-pull jacket work, this geometry is the right one.
2) Can a left-handed electrician open the Klein 44213 one-handed?
Yes. The flip lever is ambidextrous and opens with one finger from either side, and the bearing-assisted pivot carries the blade the rest of the way. That matters when one hand is on a ladder rail or holding a conductor. The frame lock is the standard right-thumb bar type, so left-handed closing takes a little more deliberate technique than opening does.
3) Is 420HC steel good enough for daily electrical work, or should I get a higher-end steel?
420HC is a high-carbon stainless that trades some edge holding for corrosion resistance and easy resharpening. For a knife that lives in a pouch, gets wet, and cuts abrasive PVC jacket and cardboard, that is a sensible trade: the 44213 dulls sooner than a premium powder steel but you bring it back on a basic stone in minutes and it will not spot up in a damp truck. Klein lists the blade as sharpenable rather than a replaceable-cartridge design.
4) Can the Klein 44213 knife be tied off for work at height?
There is a lanyard hole in the handle for tethering, which is what most utility and tower crews require for anything carried above grade. At 0.143 pounds it is light enough that a tether does not fight you. Klein does not supply a lanyard or tool tether with the knife, so add one to the order if you need it.
5) How does a frame lock compare to a liner lock or a slip joint for a work knife?
A frame lock uses the handle slab itself as the lockbar, so it is thicker and takes more abuse than a thin liner, and your grip pressure pushes it further into engagement. That is why it suits cutting where the blade may torque or bind, like sawing through banding or duct insulation. A slip joint has no lock at all and folds under back pressure. The 44213 pairs that frame lock with a stainless steel skeleton handle rather than scaled plastic.
6) Is the Klein 44213 a replacement-blade utility knife?
No, it is a folding pocket knife with a fixed, non-retractable 0.13 inch thick blade you sharpen rather than swap. If your crew is standardized on snap-off or trapezoid blade changes for drywall and carpet, this is not that tool. Buy it as the pocket carry for cable and general cutting, and keep a cartridge-blade utility knife for high-volume abrasive work.
7) Will this knife ride in a pocket without printing or snagging on a tool belt?
Closed it is 4.6 inches long, 1.6 inches tall and 0.6 inches wide, with a low-carry pocket clip that drops the handle down into the pocket so very little sticks above the seam. Combined with the skeletonized stainless frame at 0.143 pounds, it sits flat against the leg rather than hanging off a belt loop.
8) What model number do I order to standardize this knife across a crew?
Order Klein Tools 44213. It is a single-configuration item with one blade length, one steel and one handle finish, so there are no handing, size or finish options to specify. That makes it straightforward to issue the same part to every apprentice and journeyman on the job.
