For a few years now, we’ve made no bones about that fact that the razor knife we use around the shop is the Irwin Pro Touch. It’s light, comfortable, and feels good in the hand. Bostitch now has a knife that will see equal use in the shop — the Twin blade.

We’ve seen it around, but only just recently were we talked into using one. Surprisingly, it feels great. Though it is heavier than the Pro Touch, the grip and balance feel good in your hand. That alone wasn’t enough to sway us, however.

What did put the Bostitch over the top was the second blade. Unlike the razor commercials you see on TV that keep adding blades until they look like the back of a 80’s Nissan Z, the Twin Blade boasts two very workable bays that sport any standard razor type, like, in our case, a straight and hook blade. Add to that the width of the knife is still very trim and comfortable to hold, and it becomes clear this is not a gimmick.

Each blade has a slider on the spine, and despite looking like they’re too close together to operate easily, that’s not the case.

What Bostitch has done here is to actually stuff more functionality into an already solid platform. The trouble is it’s so subtle you might not notice it sitting on the shelf. There is also a Stanley version if you like silver better than mustard color — it’s exactly the same knife and can be found about 2 pegs over at the local big box.

Street pricing start at around $10.

    I’m wondering how susceptible this tool will be towards jamming of the unused bay when cutting things like tarpaper/shingles or sheetrock. If it tends to jam up a lot the convenience of two blades will be outweighed by the lost time clearing out jambs.

    We’ll probably give this knife a try. Having the 2 style blades in 1 knife seems handy.

    Some of my guys have been knives that have handle guards (bails) with “bowtie” blades – but wish that the blades could be made to retract.


    I’m not sure that you can made a double sided bowtie blade retract – but would like to hear from toolmongers who have seen such a knife.

    I just discovered from an electrician friend how handy that hook blade is for doing wiring, and to have both blades in the same place…. I’m in!

    I have one and I like it. At $10 including 4 blades, it is a good value. Although, with the physical unit I have, it is very difficult to install/change one of the blades. I am returning it to Lowes for another one.

    Lowes carries the Bostitch hand tool line. (HD does not). I also purchased the Bostitch 35′ tape ($35), torpedo level ($20) and reversible nail set ($6), all nice tools with innovative, useful features.

    I know when I reach for a utility knife in the shop, the first thing I think is “is this knife to heavy for me to use?”

    There must be a dozen different utility knives scattered around the shop. Craftsman, Stanley, Taskforce (Lowes), other brands… I can’t think of one that doesn’t do its job. I think I like the Taskforce ones the best because they’re firetruck red – and thus easy to find!

  6. ttamnoswad says:

    I still don’t understand why these traditional utility knives are still used. The point dulls very fast and it takes a clumsy effort to change the blades, meaning that people never do, therefore they are perpetually dull. New blade a day minimum.

    I haven’t used one for over ten years since I started using auto loading snap off type blades. Of course it has to be a good handle, olfa, or the good stanley version, not the cheap throw away plastic ones.

    As for hook blades, ok, thats a specific use that deserves a dedicated pouch on the tool belt/carrier.

  7. Jim says:


    Agreed, the long snap-off blades are the way to go. I have several different style of Olfa knives around the shop. They are very nice. Specifically because I can extend the blade out 2-3″ to cut a piece of foam or square cut a piece of rubber seal in one accurate downward motion.

    I purchased the dual blade Bostitch only because of the two blade feature. Having a hook blade at hand, and then being able to immediately change to a straight blade is convenient and often has its advanages.


  8. Jim says:


    I would like to know how you were able to have both blade outs as shown in the second photo. The design is supposed to prevent this from happening. The one I have will not allow this. I just tried.

      Hi Jim.
      I actually bought this knife specifically so I could use both blades at the same time (to make two parallel cuts simultaneously). After playing with it for a bit, I found that if I loosened the screws just a bit, both blades would come out.
      Off the record, I modified mine (thus voiding my 100 year warranty) so I could tighten the screws completely and still have two blades open.

    I think the olfa snap offs are great, I used the larger square handled ones. Unfortunately, the morons at my place of work think otherwise. I’m an underground electrician and management has ruled that these types of blades are too dangerous for us to use. This was caused by too many knuckledragginh miners cutting thick hose while laying it across their thighs and then extending the olfa to it’s full length!!! Guess what happens next.

    It really pisses me off as I know how to safely use a knife, as do the other electricians on site. Ever tried skinning 2/0 GGC (solid rubber 1 3/4 inch thick) cable without a razorblade knife!!!

    I’d like to see these guys run a hospital. Tell a heart surgeon with thirty years experience that he can’t use scalples.

  10. Brau says:

    Have an Olfa, but the ones I use most are no-name-cheapo’s ( y’know, the solid metal kind you have to open up with a screwdriver) I’m not worried to lose in the sand, down a wall-space, etc,. Haven’t seen a mechanism yet that can’t be jammed up beyond use after cutting drywall, and I don’t like snap blades for heavy cutting tasks either. For each job there’s a right knife, and to me this Bostitch looks like a great knife for an upholsterer.

  11. Jerry says:

    Have to ask the same question as “Jim” – “how you were able to have both blade outs as shown in the second photo.”
    The manufacturer promotes, “Interlocking blade sliders ensure only one blade is extended at a time (patent-pending)”
    Inquiring minds want to know.

  12. Jerry says:

    Looking on Lowes website, I see this knife plus a very similar one called, “Bostitch Twin Blade Roofing Knife”. Looks about the same but from the pictures, it may have a bit more of an angle to it. Comes with the same blades as the one showcased here though.

  13. IronHerder says:

    Just to pass along someone else’s idea: a millimeter or two of the tip of an ordinary utility knife blade can be broken off with pliers after it dulls. Voila! fresh blade. This makes snap-off blades seem more wasteful than necessary, maybe, as the snap lines could be much closer together.

  14. rob says:

    Used to do PR for these guys and have used their Flip Knife. Replaced the hook blade with straight blade.


  15. Eric R says:

    purchased two of these at the contractors home show late spring. We love em. The release button is a little awkward to use, almost like they could have increased the tolerances. When they wear out i will buy them again.

  16. ambush27 says:

    I can’t imagine any knife good enough to change my mind about the best box cutter. Of course just because I can’t imagine one, doesn’t mean that it can’t be built. I love the Olfa ratchet wheel because it has eight blades, is infinitely adjustable with one hand and because it feels good in your hand. Of course for fine work I prefer an X-acto style knife.

  17. Jim says:


    I understand your comment. But, if I was cutting shingles all day while wearing gloves or opening bags of concrete to empty into a mixer, I do not think an Olfa rachet wheel cutter would be my first choice.

    A utilty knife is more than just a box cutter.


  18. Sean says:

    WOOOOO! I’m going to go buy one of these TODAY. I’m a flooring guy and although I’ve never liked the retractable knives this is cool enough to give one a fair shake on the floor. Many of the materials I install work better with the hook blade and with this I can have just the one knife. Hope it works well.

    Thanks ToolMonger!

  19. Yuri says:

    Oh my God! This thing is ridiculous, go ahead just try to install the blades, reliably, repeatedly. Awkward? Yes. Bostitch actually put out a patent on this… ummm.. contraption. If the designers actually tried their invention I’m sure the nurses station was unusually busy that day.
