Perhaps you are too "full contact" on everything you are working on and need to be a little more careful.. How about looking around for a few seconds at the area you are going to be working on and assessing anything that looks dangerous and working safely around it..
If you know Bikes have a lot of Ty-Wraps on them and of course, the people who installed them did it badly and left that really sharp end on the wrap, get some little Excelite GA54 cutters that have flat angled cutter blades that will cut a Ty-Wrap perfectly flat when tightened and leave no sharp edges.. I cut those things off all the time wherever I see them on any Ty-Wrap, so the next person wont get nailed.. My pair is small for use in Electronics, and the plastic handles are a light green color.

Im not referring to those lame cutter things that look like little pistols that pull the Ty-Wrap tight and somehow break it off..
Having worked with huge cables above and underground and all the De-Marcs they end up in, above ceiling, raised floors, etc., you see zillions of Ty-Wraps and it has always defied logic how people can install them badly and leave that nasty little sharp point of plastic that will seriously cut through anything that rubs across it .. It is definitely a serious accident waiting to happen...
Just have to be really observant and try to put your hands in those tight places easy and not rush stuff..
I also use black nitrile gloves, and if they are not really thick and tight, you can get a pretty good "feel" for things and this may help to a point..
I personally use Neosporin in the tube for overnight with a bandaid for cuts if I ever get any and it seems to help healing faster and takes away the pain...
Good luck !
