Of course, the knife will make a cleaner cut, you won't even know it's been cut(maybe)...read a story about a wife who cut off his husband's penis and he didn't notice till he felt something wet on his bed...
i guess the science of being cut without being noticed is very weird.. coz you don't feel the pain until you notice some chills or something wet, i would of thought that you would feel pain first lol
haha...no,i will prolly try when i start uni it's quite bothersome sometimes to see someone pen spinning during the whole class!!
wow i can only do like acouple easy tricks.. and my friends get annoyed cuz i drop my pencil every couple secs xD
