All About Pocket Knives

After going over a year without finding a Jumbo Jack found my second one this month, a Robeson 12250, nice unmolested condition with an etch, I think it dates 1910 to 1920.

Very nice, John! What;s the closed length, on a Jumbo Jack?

Wow! Nice find.

Thank you, jumbo's run 3 7/8" to 4 1/4" or so, what really sets them apart is their mass, usually wide, thick, heavily built.

That is a great find, John; congrats!

That's a beauty!!

Amen to all the comments!

Amazing!! I have never seen that etch before.

Excellent find John! What does the third line read on the primary blade tang stamp? Congratulations

Great looking knife!

Is the spear twice as thick as the pen blade? On Jumbo whittler's, the spear rides on two springs that each of the smaller blades ride on individually, that's why I ask.

The spring for the main is twice as thick as the pen, both blades have bear trap snap.

Thank you all for your nice comments

That spear is killer!

Now that is beautiful!

Beautiful old Robeson! Well done.

Awesome find. A beaut for sure!

John , finding a Robeson in that condition in any pattern would be a great find. The simple beauty of the ebony handles and the unique blade etch just send your knife over the top. I bet she is a nice handful. Enjoy that knife. Some of us here will be a little with envy. Steve B.

Nice find John. Those big jacks are my favorite. I have a bunch of 99's.

Thank you all

Steve, totally agree, the large amount of ebony with a large shield is such a simple classy look, most of the Jumbo's I've seen have been ebony or dark cocobolo, I have seen one in jigged bone.

I have seen that etch before, but on a straight razor and I’ve seen that three leaf clover logo on an old knife box.

These big jacks from Robeson are most often etched BULL DOG and I have seen one etched, KEEN EDGE.

There is a similar knife, though somewhat smaller with a beaver/file etch.

Later ones have smooth black composition handles without a change in pattern numbers.

I think the OP knife is quite old and absolutely beautiful.

If I owned one like that, I would eventually die still owning it.
