Has this been done on a knife?

I like the idea of an unobtrusive, cross-head driver which doubles as a glass breaker. Makes sense.
 
Multi-tools never work as good as a single, purpose-built tool. Sure, if it's all you have on you or it's the top of the ladder, use what's at hand--I spent years with a Gerber Multiplier on one hip and a Leatherman on the other. I couldn't be sure what hand would be free, and a different tool mix was nice. But once your philips lobes are stripped out, you have a problem that's going to need more than just slapping in a new bit. In order for a knife to function as a screwdriver, it has to be able to take a serious amount of torque. If the bit is going to be unobtrusive yet long enough to use, you might be talking about some sort of extending mechanism. You will be trading off more handle real estate for less blade length, and the weight will be likewise creeping up. Space age materials will offset these problems but make a niche item into an expensive niche item. A small multi-tool and a ResQme are a cheap, light combo that are hard to beat.

Well there are many folders out there currently with integral glass breakers, just figured why not utilize that same space with a phillips head shape instead of a plain breaker. I wouldn't want something that is "removable" but rather integral.

Most worth while glassbreakers are carbide. Most steel glassbreakers i view as ornamental or simply a defensive weapon. A phillips imho would run too much risk of deformation. And i dont see many glassbreakers that are integral to the handle.
 
the most reliable glass breaking tools are usually consisting of a small nub/conical shaped piece(s) of porcelain or certain ceramics; the next best are carbide compounds and lastly steels.

If a philips head was made out of steel, I'm sure it would work. It probably has not been done because they work better as seperate, dedicated tools (glass breakers and screwdrivers)
 
What is preventing the Phillips head from being made of carbide? So better tools? So why do multi-tools exist? They aren't better than any of their dedicated components. By integral, I meant not readily removable.

It would be pretty limited in it's use, too short and it would make for awkward lateral pressure when tightening a screw. If there was a market for it, I think someone would have already made it.
 
Maybe, maybe not. Drivers on multi-tools are no less awkward. I'm not going to make it, but maybe someone will give it a go.
 
The guard to Rambo 's knife had a phillips on one end and slotted driver on the other. Something, I didn't know until much later, as Im not sure he ever used either. Probably, though.

I know it's been done; I can't recall at the moment though. One of those new first response knives.
 
If you need to break a car window, hit near the edge of the window. I know this is counter-intuitive, but the glass is tempered to be hardest in the center.

Well, in the center there is a more even distribution surface area to spread the shock. Near the edge, the pressure has to radiate outwards from the braced area which causes the pressure to load unevenly and fracture.
The bracing of a corner also allows for the window to flex less and absorb less shock.

You are really limiting yourself.

Seriously, I guess if you have a glassbreaker on the end of the handle, why not make it philips-head shaped? It couldn't hurt.

Now I see how erroneous my limited thinking was. Thanks, r8shell r8shell !

That comic is pretty kewl, wasn't the idea for it floated to Mr. Medford by our very own Kelama? Multi-talented, that one.

I wasn't aware of the story behind the comic, but it just goes to show how creative ideas can flourish in a positive environment.

Hey Mark- I'll take a couple, bro! :afro:

The funny thing is, is that I had actually spoken with Greg awhile back & suggested the idea for a comic book. The impetus for this very cool idea: "THE 12 DAYS OF MEDFORD"

Jack Knyff, is none other than the American version, of the Canadian version, of Stabman.

Greg read that thread, & loved it! I also sent Greg one of Stabman's books...and the rest is history.
