I bought one of the Boker magnum sweeney Todd's as a pocket knife. The knife acts like a true razor in that it pivots right through. No lock back feature.
So I modified mine a bit, making a proper thumb notch area.
Laid two pieces of tape on either side of where the spine is most prominent and spent a bunch of time on the stones..
Certainly not the long lasting edge of every other razor I own, but it does shave.
And covers my face in one pass too, lol.

It's as close to a two minute shaver as I own.
Not a testimonial or recommendation to buy one of these to shave with!!!!.
I just had some fun...
Cheers.
