Great serving thread - nice and simple, nbot much to say, but durable, easy on th ewallet, and worked perfectly when installing th epeepsite on my funky 'ol Bear Polar LTD, circa 1972. Great old bow, and this serving thread did not let it down.

Bought this to tie in the peep sight on my bow. This was the cheapest serving thread I could find and it works just like the more expensive stuff. It's a little more flimsy than the more expensive ones, but that probably just has to do with the gauge of thread. Either way, it worked well for what I needed it for and it is still holding strong after a couple of months.

It works well for serving in nocks and peep sights. It is a very small roll, smaller than a regular thread spindle. The pic makes it look bigger but its not.

Good serving. It feels very strong. Haven't had it break. It's very nice to have around if you need to redo your peep sight.

Much more durable than the serving that originally came with my bow string. The factory-original serving came apart after about 100 nocks/shots. This is still going strong after 500+ nocks/shots.

The string worked great. It can get frayed at the ends fairly easily but stay together good enough to do the job just fine. Would recommend it.

I ONLY BROKE IT ONCE. TRIED TO PULL TOO MUCH UNDER MY WRAP FOR THE END. I'M GOING TO USE THIS TO FIX A COUPLE OF FISHING POLES AS WELL.
