A true gentleman knife.

Behold the Mother of All Swiss Army Knives, a multi-tool created by John S. Holler in Germany around 1880. The knife actually predates the Swiss Army Knife, which started production about a decade later in 1890.
The knife has 100 functions, including every types of blades imaginable. It has a serrated blade, dagger blades, shears and scissors, an auger, a corkscrew, saws, a lancet, button hook, cigar cutter, pens and pencils, mirror, and straight razor. You can even use this tool to tune a piano, as it has a piano tuner built in. Hungry? It's got a butter knife so you can butter your toast.
But that's not all: This is a knife you can actually bring to a gunfight. It has a fully functioning .22 caliber five-shot pinfire revolver. And as if that ain't enough, the tortoise shell handle covers of the knife open up to hold picks, tools, and even mini folding knives.

The flip side of the knife opens up to reveal ... a small crucifix knife, perfect for killing vampires!
Sadly, it does not have a bottle opener. That's because the bottle cap wasn't invented until 1892.

Amazing looking knife a real testament to the craftsmen of the day, was probably made for the Exposition Universelle (1889) - Wikipedia, the free encyclopedia as this would have been around a similar date.

I hope you don't need that gun in a hurry.

I was thinking that thing is priceless ........ and then it occurred to me that it probably really is. One heck of an example of craftsmanship at its finest.:bow

Thank you for giving us the example of a time when craftsmanship was king!
I appreciate the posting.

Thanks for sharing. It doesn't have a bottle opener, but it have a vimpire dagger, that's all right in my book! I can spent a lot of time just looking at the thing. Does any body else get bother by the chip on the straight and wants it honed out?

Double O

I have one just like this. :p

Hahahah Talk about overkill

I'm going to have to say no to this knife as there's no USB memory stick or compass, so I'll pass on this. :D

Wonder if the knick out of the straight blade will hone out......
