I know this probably won't help much, but How many shaves does each razor have on you so far? Leg hair is a good deal tougher than facial hair, and there's more of it, so that may just be eating the blade quicker?

Also, what I did was Put a swivel clip (Like on any key chain) on the end of my strop that used a thong and bead attachment... That way, even when the cord twisted, it woudln't effect the strop...

Lanyards Hardware Attachment Options- Swivel Hook, Key Chain, Key Ring, Badge Clip One of these, Take the lanyard end (the end that clips on to things) and clip it through the top hole of the strop, then cut the lanyard off, and tie a string loop through the rectangle end, and then tie that to the door handle. Voila, now it rotates easily, this makes the strop rotate with the blade, so you usually have good contact, even if your wrist turns, and it takes torque tension off of the back of the strop... YMMV But it worked great with my TM Practice strop

I am a little rambly and unclear this early... So if you have any questions about that, or need me to make something a little clearer, let me know.

Good luck, Cassie!

Cheers,
Jeremy
