Last year on a thread on small game points I posted a trick I use for recovering points from boot top breaks. I got to recover three judos in the past two weeks (yep, miss a lot and we have lots of rocks out here).
I tied a piece of dental floss to the shaft and twist it to the shaft for about 5 inches. i glue the other end of the floss in the point glue. When the shaft breaks, the point is dangling on the end of the floss-saved me about $9 bucks this past weekeend as i lost no judos. The floss does not affect anything, but sure makes it easy to find the point.
I also make cheap blunts: take a 9mm case, heat it until it is hot and then drive it on a target point.. When cool cut off the web end of the casing. It will leave you with a blunt that weighs just a little over the weight of atarget point as the thick and heavy part of the casing is removed, leaving only a thin brass sheaf. They dig in just enough not to lose many.
