i'll never have the means to own some carbon fiber super car. ever.
but my mountain bike has been great!! i think i am on year 3 with it now. i have crashed several times. one time, we all went down this steep hillside in a blur of human and orange painted carbon fiber. bystanders helped me to my feet and then forgot about me..they went over my bike. barely a scratch. that stuff is tough!! some dude wiped the one crack they did find with a piece of cotton pad..it's all okay. they did suggest i paint it with some clear nail polish. ( "huh, i'm okay too..the bleeding will stop soon,but if you're done with that cotton pad...")
anyways, i'm sold. sold enough to buy a carbon fiber compound hunting bow. the price was staggering, so i opted to buy last years bow. from a total stranger. to complicate things, i am switching hands. yes, i bought a left hand bow. i am STRONGLY left eye dominate, so this is a switch i think i should have made years ago..or hell, started with. i held a new one at the store and fell in love. the thing is stupid light. and rigid beyond comprehensions. it feels way stiffer than my current billet aluminum one. (i know its in my mind..it more like the weight/stiffness ratio, i think). one of the selling points..carbon fiber doesnt feel cold in winter. my alum bow sucks the life out of my hands hiking in the snow. not fun.
i know very little about carbon fiber. blows my mind they can make what they do with it. at this point, i'd buy a carbon fiber handled hammer

a contractor offered me a brand new carbon fiber hardhat..i declined for ethical purposes.
