The FRENCH HAMMER was specifically fabricated for riveting while constricting and building the AIFEL TOWER IN PARIS. It was not made for forging in first place , in the fabricating the tower of various sizes of angle iron and riveting them (the whole tower is riveted) they could not get to the rivet with REGULAR (GERMAN) cross pien and because of it the pien is off center and a bit longer.
I personaly do not like the phrase '' it is good for me'' or ''the hammer is personal preference'' many times those phrases are covering lake of information and using the hammer not in the rite way.
If one takes a ''hofi'' hammer (they are produced to day by many people in the USA) and hold it NOT in the rite way he will hit his knuckles and damage the hand. If one wants to use the HOFI style hammer one MUST learn how to GUIDE it. I am not HOLDING the hammer I am GUIDING the hammer and there is a big different between the two.
I am 73 now forging professionally some times 10 hours a day moving lots of steel
never used a rounding hammer or a diagonal hammer I personally do not know why one needs them for 95% of my forging is done to day with the ''HOFI '' cast hammer
which I find the MOST BALANCED one. IF one do not know how to use the pin of the hammer (which is for me 30% of the forging) he must learn before saying I DO NOT USE THE PIEN go and learn how to use it.
ALL this is said to offend no one but only to make people learn and think. If one of my student will come up to saying '' I have found a better system of forging'' I will instantly say '' show me I want to learn'' !!!!!!!! By the way I am working now on developing a new and more balanced hammer for forging but this will take more years to finish.
ALL the rest is in my 1000 BP.
Tomas Dean you do not have to apologize all the time. The Hofi system of forging is thought now in many places in the USA on top of the place in NY that I teach just to name some of them , the community college Austin Texas by Bill Bastas, Portland by Ken Marmelstien, North Carolina by Doug Merkel , the Ozark and more.
Back to the FRANCH hammer .This hammer is still being developed into more sophisticated shapes. Just a month ago when teaching in Germany, I came across a new shape of the hammer with many more small things that are different then the original one, they are also developing the hammer and going into the future (the handle is made out of kevlar).
And last word .The SWEEDISH hammer is the less balanced hammer that is existing! it was not constructed for forging. The Swedish HOSHA made a research '' which of the HAND TOOLS is causing the most damage to the human body (because the Swedish government is paying attention according to the damage) AND THEY FOUND THAT THE HAMMER IS MAKING THE BIGGEST DAMMEGE!!
I do have the research with me.
