Very sad but good lesson. How did the two older fellows do after I left?There's a testicle sac surrounding each testicle. Use a tweezers tool (tweezers end of the scalpel tool in the Chinese tool set) to grasp a tiny portion of the sac to tear the sac. Once the testicle is exposed, one can use the tweezers to pull and twist (not my favorite method but sometimes necessary) the testicle free. The only thing holding the testicle will be the vas deferens. If you're using a straw tool, the same sac must be removed first. Using the straw tool is similar to grabbing and pulling. Be careful, though, as the straw may cut into the testicle when one pulls on the wire/line/thread. If the wire/line/thread is not at the base of the testicle, because the operator has the tool over the sac and the testicle, the sharp edge of the straw may cut into the testicle causing a slip.
With practice, the wire tool works better than the other tools because there is immediate feedback to the operator's fingers telling him/her where the wire is and when the resistance ends. The single strand has the best cutting ability (rather than a double wire, thick wire, or a plastic fishing line). Using the wire tool well requires practice. Watch youtube videos. Watch people use the tool. It's elegant because it's simple and it works. We are rarely experts the first time we learn a new skill. If one can't get the wire tool around the testicle, the sac surrounding the testicle is probably still intact. Tearing the sac at its anchor points, the ends closest to the artery, is riskier than tearing the sac near the center of the testicle.
