Klein Tools 44136 – Frequently Asked Questions

1) What replacement blades fit the Klein Tools 44136 utility knife?
The 44136 takes Klein utility blades 44101 and 44103. Both are standard utility blades, so you can stock one box for the whole crew. Swapping them is tool-free: the blade removal/insertion slide button releases the blade without taking the knife apart.
2) Does the self-retracting blade stay out while you cut, or do you have to hold the slider?
You hold it. On the Klein 44136 the blade fully retracts into the housing the moment the slider is released, so it is never left exposed on a bench or in a pouch. That is the safety trade-off: good for reducing accidental cuts, but if you want a blade that locks out for long repetitive cuts, a fixed or lock-back utility knife is the better tool.
3) Can this Klein knife strip wire, or do I still need a stripper on my belt?
There is a wire-stripping notch built into the 44136 handle, which covers quick stripping tasks so you are not reaching for a second tool for every cut. It is a notch, not a gauged stripper with sized holes, so for repeated stripping to a specific conductor size a dedicated wire stripper is still the right tool.
4) Will this utility knife work for tethered work at height?
Yes. The 44136 has a lanyard hole built into the handle for tethering, and the tool weighs 7.0 oz (187 g), so it is light enough to hang off a harness or bucket lanyard without dragging. Combined with the auto-retracting blade, it is a sensible choice for aerial and bucket truck work.
5) What is the Klein part number I should order for this self-retracting knife?
Order Klein Tools 44136. That is the manufacturer part number for the self-retracting utility knife with the wire-stripping notch and yellow handle; the 44101 and 44103 are the blades, not the knife.
6) How big is the Klein 44136 knife in a pouch or pocket?
Closed it measures 5.672 inches (14.4 cm) and overall length is 5.75 inches (14.6 cm), with a 1 inch height and 1 inch width. That puts it in the same footprint as a standard utility knife, so it drops into a normal knife slot on an electrician's pouch.
7) Is a bright yellow knife handle just cosmetic, or does it matter on a jobsite?
The safety yellow handle on the 44136 is about finding the tool and identifying it. On a dim panel room floor, in a gang box, or in insulation, a yellow body is far easier to spot than a black one, and it makes tool accountability easier when several trades share a work area.
8) Will the grip hold up with gloves on or wet hands?
The 44136 uses soft-touch rubberized no-slip regions on the handle specifically for control with wet or gloved hands, which is the usual condition on electrical and outdoor utility work.
9) What is the blade made of on the Klein 44136?
Steel blade. Because it runs the standard Klein 44101 and 44103 utility blades rather than a proprietary shape, blade cost and resupply stay simple for an MRO stockroom standardizing across a facility.
