Shadow patterns.

Here's a shadow of sorts.

This one is very interesting. Who made it, please?
 
I am surprised at how durable the shadow pattern is compared to the bolstered patterns. Could someone please enlighten me as to Tony Bose's explanation for this? Anyone else's explanation would be just as welcome BTW.;) It just seems counter-intuitive somehow, that an unbolstered knife would not hold up as well as a bolstered one with use. At the very least they seem to hold up just as well as one another and the shadow patterns seem to display a remarkable durability over time.
 
In support of the aforementioned testimony of Tony and Kerry, Todd Davison mentioned to me at the Blade Show that he had done some testing on one of his micarta scaled shadows and that short of breaking the blade, he couldn't get the knife (frame, pin, pivot) to fail even with a goodly amount of torque applied.

Indeed, there is a pic floating here on the forums of it being done. I was really impressed. The pivot pin that he used much have been super strong to resist bending.


God Bless

The pivot pin doesn't have to be super stong - just really well peened into the washers - with a well fit blade tang with no side to side play. Also, the typically used stainless pivot pins will work harden nicely during peening if handled properly. The strength of a well made shadow pattern is in everything working together. If you use the Bose construction of a precisely fit stationary pivot bushing which you can really hammer down the pivot pins and liner/scale/washer sandwich against, the blade tang really has nowhere to go sideways - which is the only way it could bend or damage the pivot pin. With a micarta/G10/G11 or similarly strong scale material glued to the liner, you have a very strong continuous structure with no real weak points -- stress is distributed nicely over the whole sandwich.

Note however - a shadow made *without* liners is somewhat weaker -- even if the scales are perfectly fit to the blade, the tang can still dig into the much softer scale material - allowing side to side movement under pressure - which allows the pivot pin to be damaged and creates a sharp stress point in the scales at the end of the tang. Even so, even without liners, a shadow can still be pretty darn strong with strong scales.

Oh yeah - Tony's post on it a while back, if I've got the link right:

I have no idea. There's not a stamp or mark on it. The nickel silver on it looks to be German to me because of the color. I posted it on BRL's forum but no thoughts.
 
jackknife & all,I think you know its a safe bet to say I'm a shadow fan.
I could barrage this thread with custom shadow slipjoint pictures.
But how 'bout just one,on a Saturday night.
A T.Bose stockman,certainly something to see.
