My wife and I have been noticing razor blade like cuts on my penis the morning after PEing. I get them where my first clamp is positioned and where the second clamp is positioned. We never had this problem until my recent gains. After third and final set of clamping, my penis is very engorged and we have to remove the clamp by sliding the open clamp off to the side of my penis carefully because it is holding my penis tightly even when opened.
If you look at pic Clamp-1, you will see a raised seam where I am pointing to. Once your penis becomes pipe hard in the clamp, the slightest seam can act like a razor when sliding the clamp off. All of my clamps have this, and one of them has a recessed seam which acts the same as the raised seam, like a razor blade.
Look at pic Clamp-2 and if you look carefully, you can see that I have smoothed that area with 400 grit wet/dry sand paper. I also did the corners being careful not to ruin the integrity of the clamp. I then took a cotton cloth and buffed the area. Problem fixed, no more cuts.
I have included pic Clamp-3 to show how I prepare my clamps. I cut .75 inch strips of mouse pad. I then put a dab of Marine cement on the inside diameter just under and right before the teeth arm and on the ratchet area about .25 before the opening. Do not glue the pad on the hinged area because the clamp will become uncomfortable when it is tighten on the penis. I use marine cement because it dries within 15 minutes and is water proof so that I can clamp while showering. I will now include sanding the inside teeth arm to the preparation of my new clamps. A couple other important things, if you notice the on my clamps, the rubber side of the mouse pad is glued to the clamp and the fabric side is what goes around the penis. I once glued the fabric side to the clamp and the rubber side gave me a sore kind of like a burn at the base. Also, cut the strip a little long before gluing to the clamp. After the glue is dried, trim the padding .25 of an inch longer so the padding over laps on the teeth arm and is .25 longer on the ratchet side. If you trim the padding right at the beginning of teeth arm and at the opening you will get the hell pinched out of your penis when you tighten the clamp to the last couple of clicks.
Hope this helps.
