This tool is nice for dogs, but useless on the small ticks and you risk ripping the body of a well fastened tick off leaving the head in your body just before you empty its guts into your blood stream. Tweezers are a no no, as you generally squeeze their guts into you blood stream as you grab them.
LOL! You watch way too much YouTube!
Considering the literally dozens of ticks I've removed on myself and others and pets, I think you are mistaken. The Tick Key is an awesome tool. Look closer. Here is another link for new readers.

Like any other tool, it must be used properly. The tool is used by putting the body of the tick through the large hole and then sliding it until only the mouth parts are in the tiny narrow part of the tool. Then the tool is pried upward but only enough to pull on the tick's mouth until it let's go voluntarily. It's a slow process but the tick will not regurgitate if handled this way.
I tried the thread trick once 40 years ago and then decided it is for people with patience I don't have. It's also too easy to get the thread on the head instead of mouth parts. I agree that tweezers are a poor choice because it's too hard to grasp just the mouth parts.
I have also tried a tick shoe which works similar to the tick key, but it's too bulky. I prolly have a dozen different tools I have tried. The tick key is the best hands down.
I keep a tick key in my wallet. It's gets used several times each year. While it's quite thin, I'd pay good money for a titanium one that is even thinner and takes up even less space in my wallet.
