Klein Tools 44052BLK – Frequently Asked Questions

1) How big is the Klein Tools 44052BLK knife when it's open and when it's folded?
Folded, the 44052BLK measures 3.5 inches (8.9 cm) closed, and it opens to 6.125 inches (15.6 cm) overall. The blade itself is 2.563 inches (6.5 cm). At 4.8 oz (136 g) with an anodized aluminum handle, it rides in a pocket or a pouch slot without much bulk.
2) Does the blade lock open on the Klein 44052BLK, or does it just hold by friction?
It locks. The 44052BLK uses a lockback mechanism, so the blade is held rigid in the open position until you press the spine release to close it. That's the difference between this and a slipjoint pocket knife, which can fold on your fingers under back pressure when you're cutting through sheathing or strapping.
3) Is this Klein knife safe to use on live electrical work?
No. The 44052BLK is not insulated and carries no electrical rating. Klein's own guidance with this knife is not to use it on or near live circuits, and to wear approved eye protection when cutting. De-energize and verify before you cut. For live work you need a tool specifically rated and marked for it.
4) What is a tanto blade good for on an electrical or maintenance job?
A tanto grind puts a thick, reinforced point on the tip instead of a fine taper. On the 44052BLK, that tip takes piercing work, starting a cut in Romex sheathing, punching through carton board or drywall, prying open a knockout slug, without the tip snapping the way a thin clip point will. The tradeoff is less belly, so it's not the shape you want for long slicing runs through rope or carpet.
5) What steel is the Klein 44052BLK blade, and will it hold an edge on job site work?
The blade is AUS 8 stainless steel. It's a mid-range Japanese stainless that takes a keen edge quickly on a pocket stone and resists rust better than a carbon blade, which matters if the knife lives in a damp truck box or gets used outdoors. Expect to touch it up more often than a premium powdered steel, but it comes back sharp with very little effort.
6) Is the handle on the 44052BLK plastic or metal?
Metal. It's anodized aluminum in black, which is why the whole knife still only comes in at 4.8 oz (136 g) despite the metal frame. Anodizing gives a hard, non-flaking surface finish rather than a paint layer that chips off in a tool bag.
7) Is there more than one size or handle color of the Klein 44052BLK?
One configuration only. The 44052BLK is a single model, black handle, 2.563 inch tanto blade. If you're standardizing a crew or an MRO crib, every unit you order is identical, so there's nothing to specify beyond the part number.
