Neat idea RGi...

I vaguely remember doing French at school, but I never imagined those cleats could serve a purpose in my older days... greatly under rated. 

 with a keen edge, but lives in a drawer in a sock 

I have one of them... no, not the drawer and I wear SWMBO's panty hose... but, as Tattoo would point out,
 but now within view so the poor thing doesn’t get left out o the fun again!
Unfortunately I never discovered the hollow in the handle (note to myself for a new hiding place)... so I had to make a box for it...

making it further out of sight... being secreted in a drawer, no wonder I never see a smile on it's face.

If your first cut is too short... Take the second cut from the longer end... LBD
