[quote lordmarcovan]I agree with those who expressed a concern about the blade snapping, and with the previous post that says you should shorten it so you have thicker metal that is less likely to snap on you.
While you're shortening it, I would round the point down considerably, to avoid accidentally scratching the "D" off that 1916-D dime, or the "S" off that 1909-S-VDB cent![/quote]
The drywall jab saw will probably bend before it snaps. Mine are all bent! LOL
...very good observation, though... I AM a surface hunter and use all sorts of home made probes from sharpened screwdrivers to icepicks, awls and ground down knives... And I have scratched, gouged, scraped, and chunked ALL SORTS of coins and trinkets.
Over the years I've even scratched the precious stones on valuable rings and destroyed the value of some older coins.
Can't say I would advise anyone to use a probe that wasn't soft brass, if at all!
Pinpointers are a GOOD thing!
