Klein Tools 44142 – Frequently Asked Questions

1) Can you open the Klein 44142 one-handed while you're up on a ladder?
Yes. Dual thumb studs let you deploy the blade with the same hand that's holding the knife, so your other hand stays on the rail or on the work. Once open, a lockback mechanism holds the blade so it can't fold back on your fingers under pressure. To close it you release the lock spine, which takes a deliberate two-hand motion, so plan on a moment to stow it.
2) How long is the Klein Tools 44142 pocket knife when it's closed and clipped in a pocket?
Closed, the 44142 measures 3.8 inches (9.7 cm), and it opens to 6.75 inches (17.2 cm) overall. That closed length is what matters if you're carrying it clipped in a tool pouch or a pants pocket alongside strippers and a screwdriver. It rides on an integrated pocket clip and has a lanyard hole for tethering when you're working off a ladder or lift.
3) Will 440A stainless hold an edge for cutting Romex sheathing and cable jacket all day?
440A stainless is the blade steel on the 44142, and it's a corrosion-resistant stainless that takes a keen edge and is easy to touch up in the field with a pocket stone. Slicing THHN insulation, NM sheathing and cardboard will dull any knife over a shift, but 440A resharpens quickly rather than fighting you, and it won't spot up from sweat or damp crawlspace work the way a plain carbon blade will. The blade carries a satin finish.
4) Is a drop point blade the right shape for electrical work, or should I get a hawkbill?
The drop point on the 44142 is the general-purpose choice: the tip drops below the spine so you get a strong point with good control for scoring, piercing and detail cuts, plus enough belly for slicing tape, cardboard and jacket. A hawkbill is the specialist tool if most of your day is ring-cutting large cable jacket, since the hooked edge pulls into the cut and keeps the point off the conductors. If you want one knife in the pouch for cable, boxes, drywall shims and lunch, the drop point covers more ground.
5) What's the exact Klein Tools part number for this 2.875 inch drop point pocket knife?
Klein Tools 44142 is the part number, and it's a single-configuration item: one blade length, one handle color, no left or right variants to specify. If you're standardizing a crew's tool kits or writing a repeat MRO order, 44142 is the only number you need on the PO.
6) Is the lockback on the Klein 44142 safe enough for cutting toward yourself in a panel?
A lockback engages a spring-loaded bar into a notch in the blade tang and holds the blade open until you deliberately press the spine release. That's what keeps it from folding on your fingers when the blade binds in a cut or you push through tough jacket. It is not an automatic or assisted knife, so deployment is fully under your control with the thumb studs. As with any folder, cut away from yourself and keep the lock face clean of debris so it seats fully.
7) Does the Klein 44142 have an aluminum handle or plastic scales?
Aluminum, in black. That's a lighter and more corrosion-resistant handle than a steel-bolstered knife, and it won't crack or go brittle the way molded plastic scales can after a drop onto concrete. The whole knife weighs 0.14 oz (4.0 g) per the product weight spec.
