bound201 Posted June 18, 2013 Share Posted June 18, 2013 I'm making a striking stamp to mark my knives and other items. What size would you recommend? Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted June 18, 2013 Share Posted June 18, 2013 Big enough to be ledgible, Not so big to be out of place. Under a foot square :) :) Neil Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 18, 2013 Share Posted June 18, 2013 How are you going to apply it? a good size for a press applied stamp may be way to large for a hand struck stamp. How "busy" is it, the more "work" it has to do the more force it will need. Will it be used on hot metal or cold? The devil is in the details!

rockstar.esq Posted June 18, 2013 Share Posted June 18, 2013 Big question. I second the legible comment -lots of touch marks aren't and if they are, it's unclear what they're "saying". People seldom include their city and state. Unless you've got a good website, potential customers may need more to go on. A lot of knife makers etch their mark.

Herb Upham Posted June 18, 2013 Share Posted June 18, 2013 Etching works very well unless you are making purely forged knives where the detail would be out of place. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 18, 2013 Share Posted June 18, 2013 not to mention that a stamped design is also a stress riser! Quote Link to comment Share on other sites More sharing options...
bound201 Posted June 18, 2013 Author Share Posted June 18, 2013 This will be hand struck, intend to use this in hot metal, though am interested if people feel cold is better. Small quantities of items I produce so no major manufacturing going on so one would last me years.

bound201 Posted June 19, 2013 Author Share Posted June 19, 2013 So you'd recommend the etching route? I've etched Damascus is the process similar? Obviously I'd need a design to etch into the item but the steps are roughly the same I'd assume.

ThomasPowers Posted June 19, 2013 Share Posted June 19, 2013 look into electro etching for blades Quote Link to comment Share on other sites More sharing options...
bound201 Posted June 19, 2013 Author Share Posted June 19, 2013 look into electro etching for blades Do we have a good example thread for the etching walk through? I searched and looked at a couple of pages and didn't see anything. Just curious, thanks. Quote Link to comment Share on other sites More sharing options...
thingmaker3 Posted June 19, 2013 Share Posted June 19, 2013 I really wouldn't worry about stress concentration in this instance. Have a look: http://courses.washington.edu/me354a/chap6.pdf Sure, it'll take more to break something at an etched logo than a stamped one, but who here has ever seen a knife fail there? (As opposed to just repeating tales?) Stress concentration is much more of an issue at the shoulder of the tang, as one can understand by reading the reference given.
