"Loaners" and "beaters" is what the under-$20 Cold Steel knives are intended for. The Canadian Belt Knife and Pendleton Light Hunter styles work well and if you lose one, well you've lost something without much value, about the cost of a California Roll lunch at the local sushi place. Not so with a good factory knife, like a Buck 105, or a custom knife from Mr. Ingram, Mr. King, or Mr. Murr.
