Klein Tools 31737 – Frequently Asked Questions

1) Does the blade on the Klein 31737 lock open, or does it flop when you push into a wall?
It locks. The 31737 uses a lockback mechanism with two detents, 125 degrees and 180 degrees. Straight out at 180 is what you want for a standard plunge into drywall; the 125 degree position angles the blade toward you, which helps when you are cutting overhead or in a ceiling and cannot get square to the work. Engage the lock fully before loading the blade.
2) Folding jab saw or a fixed-blade drywall saw, which should an electrician carry in a pouch?
The reason to pick the folding version is the pouch. A fixed blade jab saw has nothing covering the point, and it works its way through the bottom of a tool bag or pouch over time. The Klein 31737 folds the blade back into the handle, so the tip is protected and so is your bag. The trade-off is one extra step at the wall: you unfold and confirm the lockback engages before you cut. If the saw lives in a truck drawer and never rides on your hip, a fixed blade is simpler.
3) Can you tether a Klein folding jab saw for work off a lift or scaffold?
Yes, there is a lanyard hole in the handle for tethering. At 0.543 pounds it is a light tool, but a dropped saw at height is still a dropped saw, and the tether point is there specifically so it can be attached for elevated work.
4) Is 8 TPI the right tooth count for cutting plywood and sheathing, or is it only a drywall saw?
8 teeth per inch is a coarse, aggressive spacing. It clears gypsum dust fast and it will take plywood and plastic as well, which the blade is rated for. What it will not give you is a fine finish cut in trim or hardwood, and it is not a metal-cutting blade. For rough penetration cuts and hole making in building materials it is the correct tooth count.
5) Will a jab saw like this cut an opening for a ceiling vent or duct boot?
Yes, that is within what the blade is meant for. With a 5.2 inch hardened carbon steel blade and 8 TPI you can plunge through ceiling wallboard and follow a marked outline for a vent or duct boot. Use the 125 degree lock position for overhead work so your wrist is not fighting the handle angle. For cutting the sheet metal boot itself you need a different tool, this blade is for building materials, not metal.
6) How long is the Klein 31737 jab saw folded up, and will it fit a standard pouch slot?
Open, the saw runs 11.9 inches overall with a 1.45 inch width and 1.75 inch height. Folded, the 5.2 inch blade tucks into the handle, so the closed tool is roughly handle length. It drops into a normal pouch knife or saw slot without the tip sticking out the bottom.
7) What is the handle on the Klein 31737 made of, and will it hold up to sweaty hands and repeated ceiling cuts?
The handle is plastic with rubber grips, so you get a non-slip surface rather than bare molded plastic. The end of the handle is cushioned to act as a palm rest, which is what you lean on when you are punching the blade through wallboard repeatedly for box cutouts.
8) What part number do I order for the Klein folding jab saw?
Klein Tools model 31737. It ships as a single configuration, one blade length and one handle, so there is no finish, size or handing choice to specify on the order.
