This razor was previously available in a TSR pass around and an ATG pass around.

Here is how it works:

View from the top with the little grip handles folded in. Note the star-shaped holes - they give more grip than round ones or handles without holes would.

B-P closed

The handles fold out:

B-P folded out

View from the bottom. You open the razor by lifting the base plate where it says Open here:

B-P open
B-P wide open

Then you put a blade in ...

B-P with blade

close the base plate and fold out the handles fully. Pick up the razor with thumb and index finger and you're ready to go.

B-P shave ready
