I absolutely love semantics.

Stripped heat vs stripped threads same word but this clearly wouldn't work for anything that's not loose

Thank you for your comments, we appreciate feedback and understand if you haven’t perhaps used a pair of our Vampliers you may not be convinced; yet! We would love for you to try a pair for yourself firsthand and invite you to order a pair. VAMPLIERS® Technology utilizes a patented design with vertical and horizontal serrations that leads down the inside of the jaws to the tip of the pliers. These serrations are formed, like teeth, at the tip of the pliers to create the maximum amount of contact between the VAMPLIERS® and the screw; creating the perfect “bite” around the screw’s head. See here for more information: www.vampiretools.com/our-technology/vampliers/ We would also invite you to read some of our customer reviews where they talk about the kinds of screws we helped them out with: www.amazon.com/VAMPLIERS-Patented-Multi-Purpose-Extraction-Specialty/dp/B006YJKAPQ/ref=psdc_3021459011_t2_B07BMKX4KG?th=1 for recessed screws we also have our fantastic Recessed Screw Extractor, that removes stripped or damaged flathead, countersunk, and recessed screws. www.vampiretools.com/shop/application/aircraft/recessed-screw-extractor-2-1-bit-set/ Thank you

​@@Johnny-tq9no "...clearly wouldn't work for anything that's not loose" Oh, I don't think that's so clear. For example, if you have a saltwater crocodile with the correct orthodontia handy, you could grip the croc while the croc grips the pliers, then turn the croc slowly to back the damaged screw out. Alternatively, if, for example, you live in a more deprived area and don't have a crocodile on hand, you can always turn to your trusty coconut crab to get the job done. Simply have the crab grasp the pliers in its "pincer" (prefer the dominant of the 'chelae' - the largest, usually the left), then, grasp the crab with your hands and rotate until the screw is clear of the hole. Failing even that - and I hate to think of the deprivation endemic to some areas, but, certainly not everyone can afford a coconut crab in this day and age - you might try a ratchet cinch strap, or, better, a ratcheting binder and appropriate chain & positioning to obtain the level of mechanical advantage and thus gripping force required. Then, once again, simply rotate (the pliers directly, this time) until the remains of the screw are clear of the object that factored into its demise. Ex-screws should be laid to rest in an appropriate "memorial park" after a period of mourning to last no less than 3 days.
