Case double jigging

[btrwtr]

I have always found this type of jigging found on Case Tested hawkbill knives to be very curious. It is actually 2 types of jigging pattern on each bone slab. I would think that the bone would have to go through 2 separated jigging processes to achieve this but don't really know how it was done.

I love the look of it. On Case hawkbill examples I have seen the thinner area near the bolster has an older random second cut type jigging and the thicker bone at tail end has the newer corn cob type skip jigging.

Is there any other Case patterns that have this double jigging type bone? Does anyone know how or why this was done? Are there any other companies that used 2 styles of jigging on the same bone slabs?

Sorry I don't know. But it looks cool.

Wayne, I have never noticed this. One thing I have noticed is on the 62005 tested knives the jigging is different from the 6205 and in fact different from any other jigging I have seen in the tested era. I wonder if anyone still alive knows the answer to either question?

I've never seen that before. It's interesting, curious, and odd, at least to me.
I can't imagine why it would be done.

Wayne do you think this might be some early Rogers Bone? They started making bone for pocket knives around 1900. Close to the bolsters it reminds me of Rogers.

Wow, that is quite interesting my friend.

Tom, I believe with the pattern number with "00" in it can indicate that the knife is a contract knife. I have a XX 620035 LP and a TESTED 63045 and they are contract knives made with imitation jigged bone. Some sort of black plastic or synthetic jigged to looks as if it was bone. That might explain the difference in the jigging that you mentioned. I have attached a few pics as examples.

What is odd is that I have the same knive as Wayne's, a CASE TESTED 61013 Hawkbill which was only made in TESTED era. Mine is interesting also as it has on side of normal jigging and the other side has saw cut and jigging. Not sure which they did first, saw cut of jig.

Very odd to me. Coupled with the fact that they were only made this one era, maybe CASE was experimenting on this pattern with different jig combos. Pure speculation but that is my thought. My price lists and inventory sheets are sparse during that timeframe.

Thanks for the replies all.

I have owned a number of 61011 hawkbill knives but never one with this double type jigging though I have seen many examples of this. The double jigging looks to be 2 distinctly different patterns and I can't imagine one machine doing this. Sargent's 7th edition shows this double type jigging on a Tested hawkbill, page 194 bottom left hand side of page. The knife shown there is listed as "Rogers bone" but I would not call it that and do not think that is correct. The jigging patterns both look like Case jigging to me, a standard corn cob skip type and a second cut bone type jigging. I don't recall ever seeing this variation on a XX knife, just on Tested knives.

I did have a Case tested 61011 Hawkbill that was actually a dark brown Rogers bone. I think that it was a rather rare variation and was quite different from the 2 knives I posted and the knife in Sargent's book.

Here is a picture of another example I found in completed eBay sales.

This is the jigging I was referring to on the 62005. It is only 3 1/4" closed as opposed to the 6205 which is 3 3/4" closed. The book says jigged greenbone, only Case Tested pattern I have seen this jigging on.
It is not composite.
