Dave thanks for the info on wreck kit. I've just started the retrieval portion of my dive career ;} Brought up a 90# steel winch pulley from 170'. From now on, I'm looking for smaller, more manageable items. I assume a bolster is the same as a chisel? Do you take a hacksaw and, if so, how do you keep the blade covered. I'd like to carry a small hacksaw but want some sort of sheath for the blade to avoid cutting my dry suit. I'd appreciate any thoughts or comments.
