The Rogers Bone Thread

Rogers bone?

[orvet]

The pictures aren't the best (not a criticism just fact) but it appears to me to be Delrin.
Let me lighten the picture up a little bit and see, but it certainly looks like Delrin that Camillus used.
What brand is the knife?

[Oldredbone67]

Roberson/ Camiulus

[orvet]

If you notice how smooth the handle is around the bolsters, this is generally a sign of a composite handle like Delrin.
If you look at that smooth area under high magnification, 45 X or greater, you will see little checking marks and often you will see the haversian canals. Bone is not smooth when viewed under magnification.

From Wikipedia:
Haversian canals (sometimes canals of Havers, named after British physician Clopton Havers) are a series of microscopic tubes in the outermost region of bone called cortical bone that allow blood vessels and nerves to travel through them. Each haversian canal generally contains one or two capillaries and nerve fibres.

[orvet]

This is a Robeson trapper, probably made by Camillus. This is a bit more magnification than your picture so you can see how smooth the bolsters are.

This is a knife I rehandled last year with camel bone. Even though the bone is smooth to the touch the dye in the bone does show miniature fissures and cracks that you do not see and a composite handle like Delrin. I don't have enough magnification on this to see the haversian canals but there is enough magnification that you can tell the material has minute cracks and fissures in it.

Whatever it is it is for sure NOT Rogers bone.

Thanks for the info

....I agree, t. j.!!...... ..........

I was able to mess around in my room today, I noticed that I kept wanting to pick up the epual end Rodgers Bone knives. I really like the bone handles that Remington used on there knives. An equal end knife is by far my favorite pattern, big, small, I don't really care. I gathered up as many as I could to fit into one picture. There is one stag knife in there.

Is Rogers bone the same on all knives? Seems to me that the Rogers bone on a Remington is a little different than like Rogers bone on a schrade or other variations in other companies. Is that theory only in my mind?
Thanks Keith

I'm only a month late but I thought you might like to know, those handles are a Delrin® pattern Camillus called Indian Stag.

Keith it's my understanding that there are several variations of Roger's Bone that were produced through the years. Add to that the change in it's looks as it wears in the pocket, and the dye used to color it, and you get some pretty wide variations of how it looks.

I really can't address if the bone Remington used is different. I just don't have enough Remingtons to compare to.

Thanks for your input Phil. I've just noticed that I can tell a difference in scrolling threw eBay if it's a Remington or not. I might be seeing different years production, I don't know.

I made a collage of some, what I believe to be, Rogers bone knives. To my eye, the jigging patterns only look comparable - not identical - even within the same knife brand. The left column in the picture are Remingtons. The right column at the top is stamped "Made in USA", next is a Wards stockman, Case Bradford cattle knife, Case Bradford Cokebottle, and last WR Case & Son Cokebottle. I think the similar, but randomly different look is a big part of the attraction. The Remington handles are my favorite Rogers usage of any brand of knives that I have.

The file is large so if you click on it to enlarge it will take a few seconds to download and display. The file is large because it is a mash up of 10 individual high resolution pictures. When the combined results are made smaller the individual image quality of each knife suffers some wavy edges (moire effect). There is no file work on these knives

Keith, I don't have any Remingtons to compare but here is a shot of a Case and a Camillus from the 40's that don't appear to have been handled much. Both have Roger's bone and they are very similar but do have subtle differences

[espn77]

Jerry, the wards and the case cattle knife look the same. The rest I would have to look at the description to know.

Greg, both your knives I would be surprised if they had Remington stamps.

I know very little about Rogers bone process other than what I've been told here, but, it seems the jigging in the 20's-40's seems different than earlier or later jigging?? Just my observation. I could completely be proven wrong.

[LongBlade]

I agree with you Keith ... hard to believe the jigging and even the bone looked the same over the many years they were in business... I think this was discussed abit earlier in this thread if I remember right... if not I can't imagine Rogers Bone did not change over their many years in terms of bone and jigging in terms of cutlers etc etc... ...

[espn77]

Lee, appreciate you commenting. I find Rogers bone to be very fascinating to me, for some reason
I guess it's the beauty of every pattern being different. Different depth of the grooves, different color. I wish I knew more.

[mountainad82]

Here is an older Queen #10 Heavy Jack in Rogers Bone. Love this handle material.

[carrmillus]

....beautiful!!!!....my favorite handle mat'l!!!.......... .................

Question: Is Rogers bone scales found on Germany made knives?

Question: Is Rogers bone scales found on Germany made knives?

Scott I'm no expert, but I do not recall ever seeing Rogers Bone on a German made knife.

[KnifeSlinger#81]

This utica kutmaster has nice dark rogers bone.

[peanut740]

Nice example Paul.
