Default quick question about magnesium hammers

i was watching a ron fournier dvd and he mentioned a magnesium hammer when i tried to look into it it seems to be like a unicorn everyone has heard about it but they cant be found anywhere Does anyone know if those hammers are worth the trouble or was it a passing fad that happened years ago thanks for any input ed

I guess he does not sell them anymore they where expensive , I have never owned one but they where for shaping aluminum i guess they where hard enough to work the metal but soft enough not to leave a mark plus i think it would not contaminate the metal like rusty steel . UHMW (plastic ) even wood works fine and keep your steel hammers polished . I have a really soft urethane mallet for thin aluminum also .

Default titanium ?

http://www.amazon.com/Stiletto-TB15M.../dp/B00079R1YM

I have tried a guy's titanium carpenters hammer, Light weight but delivers a blow like a much heavier hammer. I Am supposedly retired, contractor and do most of my work with a nail gun. The titanium hammers are expensive. The explanation of the hammer was that it is also like titanium golf clubs. I remember as a kid on the ranch hammering pieces of wire in the blacksmith shop on the big anvil and the wire would heat up. the compression load on the wire and hammer creats heat. Titanium does not compress as much as steel, more energy is delivered to the nail. I haven't seen any titanium body hammers. I am building a helve hammer and Minny pulmax type machine. too much tennis elbow from construction work in my younger days.

These hammers seem to defy Newton's second law. f=ma
So for the force from a light weight hammer to equal the force delivered from a heavy hammer, you would have to swing the light hammer faster. I don't see any advantage in that unless you are a person who usually damages his work with a hammer. In other words, if you refuse to change your technique, you can use a lighter hammer.

I have a set of very, very small dinging hammers that I got a few years ago. They range from about 3/8 in diameter with 1/2" faces and 1" long to 2" long with 1" faces. Long skinny flexible handles. I've got photos somewhere. They were made by a guy in Ca some years back and no longer available.

Cass Nawrocki has some similar.

These are used to move aluminum around. Lots of fast light blows in the right space, usually with no backing dolly. Metal moves but no marks. I've used them on Monique with good results.

I expect the magnesium hammers work about the same. I saw one once at a swap meet but didn't know what it was and didn't buy it.
