Tungsten carbide rings will crack instead of deform. I've heard of machinists getting their finger smashed and if you have a ring that will deform instead of break...well you end up with a deformed ring smashing the crap out of your finger instead of just breaking off.
 
Not surprised at all. I bought a Movado watch with a tungsten case; it cracked at one of the pin holes within a year. I have no idea what caused it. It's a friggin dress watch that I wore about five times. Movado refused to cover it under warranty. They don't make it anymore so I think they found out they had a problem. Tungsten is super hard but very brittle.

Yeah I do everything with my hands and I have worn it for 4 1/2 years of testing knives working on aircraft, falling lol, doing maint on the cars, build stuff, and finally it gave out.
 
Not directing this at you Chad, but I laughed when I read some of the reviews of various ones I looked at when shopping--- Definitely a lack of understanding the difference between hard and scratch resistant vs. "super strong!" ;)

I remember seeing TC rings at the jewelers' shops while looking for Angi's ring and thinking they were such a great deal... $400 compared to $???thousands.

Then I found the exact same rings on ebay for $15 with free shipping. LMAO

I bought two just in case. ;)

I'm surprised yours held up to all that for so long Chad. I have a hard time wearing jewelry of any kind and saw a guy's finger after it had been "de-sheathed" so I only wear mine when I'm cleaned up.... which is VERY RARE! :o LOL
 
Moved, as this is not KNIFE discussion.
Also, please stop posting duplicate threads in multiple areas, it is not allowed.

Tungsten and other carbide rings are ceramic. The metallic powder is pressed in a mold and fused. This is a very different thing from a crystalline metal like the tungsten carbide on a saw blade tooth or other cutting tool. They can take almost no impact without damage. Sadly, the spin doctors taut the hardness and ignore the brittleness. They become ugly quickly due to millions of tiny impact spalls. The way they are taken off an injured finger is to place in a vise or vice grip and tighten just a tad. they will snap into piece. The good news is that most of the manufacturers warrantee them completely. Contact the place you bought it or the manufacturer ( Benchmark?).
 
Lol Nick we did something similar. I bought her a nice gold band which she lost about 3 weeks later (she didnt lose the engagement ring thank god, that was pricey) so she ended up getting two of the titanium ones for like $40 or something like that.

I stick with gold for mine, I work on too much stuff that god forbid could strip my finger or various other issues and I want the medics to be able to remove my ring which can be a real issue with tungston or titanium. Granted the wife doesnt do much stuff like that so not really an issue.

Edit to add: did not know that Stacy, good to know. I was always worried about getting the darn things off in the event of an accident.
 
One tap with a hammer or a squeeze with pliers/vice grips/etc. will take it right off.
 
Tungsten or tungsten carbide ? Tungsten carbide tooling is "glued" together with cobalt .More cobalt , less brittle. You shouldn't be working with machinery and wearing jewelry !

This is a pretty solid rule to follow IMHO. I always thought it was more applicable to stuff that "dangles" like chains and such. However, like I mentioned above, I saw a guy's hand after he "de-sheathed" his finger :eek: :barf: (I doubt that's any type of real medical term, but it's what the EMT called it).

He had climbed up to get something off a top shelf of pallet racking (you know, like the shelving stuff is on at Costco). He slipped, tried to catch himself, but he only caught his wedding ring on the edge of the pallet racking.... 200+ pounds of body weight pulling vs. the skin/flesh on a finger is not a match-up that yields favorable results. :thumbdn:

I don't post a picture here because it's nasty and would probably get the thread moved to W&C... but if you're curious just do a google image search for "wedding ring finger trauma." It will definitely make you reconsider wearing a ring in any kind of working environment. :eek:
 
De-gloving is the correct term, but yours is more knife related, Nick :D

My tungsten carbide ring looks exactly the same as the day I put it on over five years ago. Not a scratch or spall to be seen. I don't wear it when hammering or working on trucks, but do for everything else, and I do a lot of work with my hands.

Also, standard ring cutters used to not be able to cut titanium effectively. I think most medical trauma centers have upgraded, but that was another plus for tungsten carbide (the ease of breaking it off and the inability for it to smash and deform into my finger).
