Questions & Answers

Does this knife have a 90 degree, flat spine that could be used to strike a ferrocerium rod?
ByNov 29, 2023
1 Answer | 
Answer This Question

Part of the spine has a square, sharp edge, but the other side is rounded from the stamping process. However, the entire length of the swedge is square and will absolutely strike a ferrocerium rod.

          If you are using it for work, on a jobsite it should be no problem. Just don't go around wearing it on your belt off the job.

            That’s what happens when you live in a liberal ran state. A 4” blade is by no means a weapon

                It would probably do okay but you would be better with one of the 25mm knives from Olfa with replaceable blades.

                  I would prefer to call it a 'resolution' to a problem but I'm in CA where we have a lot of pests that need exterminated.

                      Great dagger!
                      This is a fantastic knife, comes razor sharp right out of the clamshell packaging. Serrated blade is super useful when cutting large bales of insulation. The flat grind and the straight edge part of the blade is very good for cutting flex ducts and fiberboard to size. Steel is great, I wished there was more information on it.

                        Misleading
                        I cut this knife open and discovered the full tang is not in fact full tang. See photo below. Also the sheath sucks.

                          Now that's a knife!
                          Good durable construction. Edge holds up with regular sharpening. Thumbs up

                            Best “Hip knife” I ever had.
                            This thing takes a beating. Stays sharp really well. Is easy out and in sheath. Locks in good. Bought two extra incase they discontinue making it. I hammer on it, scrape with it, and hunt and fish with it. Had it 6 months and sharpened it twice.

                              Knife is great, sheath snaps.
                              Most of my landscapers wear your 48-22-1926 knife which is sturdy and works great. Some of them prefer this 48-22-1926 knife, but the plastic belt loop keeps snapping off the plastic sheath. I need help with this, would like to be able to purchase sheath only or find replacement sheaths.

                                Very sharp and totally durable. Better than Klein, Hilmore and Dewalt. Hands down!
