I filed mine down with a rectangle one, it looks shit but did the job. My 100mm wheel scraped. I was like WWWTTTFFF? So I filed it like 2mm and it worked and I was like YEAH MOTHERFUCKERS. I was so happy so I went to the skatepark and watched a kid try to barspin his bike onto a matress and miss and crash. I was like YEAH MOTHERFUCKER and he was like ILL FUCKING KILL YOU and I was like OH FUCK. So then I shut up and he didn't say anything. Then I aired the 12 ft about 1 ft above the coping and i was like YEAH MOTHERFUCKERS and then some other noob kid with flouro griptape come and went higher than me and I was like WWWTTTFFF? So then I tried going higher than him in the halfpipe and hit a pepsi can and the kid who missed the matress was like YEAH MOTHERFUCKER and I was like SSSTTTFFFUUU and he was like OOOMMMFFFGGG THIS KID IS A WANKER. Then we played follow the leader and he said I was quite good so I said THANKS MOTHERFUCKER and he was like THATS COOL MOTHERFUCKER. So now everyone knows us as the MOTHERFUCKER BROTHAS.
Not true BTW, I just took up story writing
