Question on 1970's 110/112 blade finish

Can anyone who bought/owned/owns a 1970's 110 or 112 [ex: dot110dot] tell me what the finish on the blade *should* look like???

Here's what I mean: A *new* 110/112 will have what appears to be an "as-ground" finish, with an abrupt transition from the semi-hollow ground section to the flat [spine] section of the blade. There is a sharply defined almost-shoulder-like line where the two differently ground sections meet.

Now...I have two 1970's Bucks; a 110 and a 112 (which just came in). The blades are both fairly used, need sharpening, and appear (to me) like someone tried to "smooth" the blade surface...but a fellow member here tells me the older Bucks often looked like that when new...with a smooth, rounded transition between the two ground surfaces of the blade...

I was planning to re-blade both knives...But if they originally looked that way, then I will just have them cleaned, sharpened, and polished...(or bead blasted, whatever the procedure is)...

Both are square-bolstered, three-brass/one-steel pinned, steel spacered, wood scaled.

I would not call either one "excellent" condition...or even "good"...but for my modest collection, just cleaning & sharpening will be sufficient...*IF* the surface finish actually was "smoothed"...

Anyone? :)

Thank you for your time! ;)
 
If I remember correctly my old no-nail-nick 112 had that smoother transition from flat spine to hollow ground and I think the blade was probably ground a bit thicker on the hollow part, I seem to remember that the different grinds were mentioned in some older thread.

Thank you, Don Luis! :D

(I forgot to mention the 112 was "no nick", but the 110 has a nick)...

Now that you mention it, I do recall someone (Joe? Larry? Jeff?) mentioning that the grind changed...and the edge angle too, IIRC...and that back then they were hand finished (?)... :confused:

The 112 has "U.S.A" on the 3rd line also, but you can only see it when the blade is 3/4 closed... :rolleyes:
 
Chickentrax,
I have a 1972 112 where the blade has not been altered. When I get home tonight I will provide a link where you can look at the blade and see for yourself. There is a distinct difference as folks have mentioned.

Chickentrax, was thinking about you and your 110s just the other day! I have as we speak, two, two dot 110s, one is a two pin that I just got at a gun show, the other is from a BCCI member, it's a three pin. First, the finish on both is the same, very fine striations, with smooth transitions all the way to the sharpened edge. The three pin is mint, so I sure it left the factory that way, the other had been used and had scratches and had been poorly cared for and sharpened, but I could tell that the finish would have matched the other.

The clip on the two pin is the longer(as per your other post), the three pin is the one that I put up against the newer ones I have and as I replied in your thread and couldn't see much difference...but I can between this two. I have a digi camera on the way and if your still interested I will post(well, I'll try) pictures of the two. I sanded out a lot of the scratches on the two dot with wet/dry sandpaper...finished with 400 grit and they match up fairly well. The steel is 440C and it took a SS edge. I'm looking forward to using it and seeing how it will hold up compared to some of my others.

Happy Thanksgiving to you all. Preston
 
Thank you also, Mike & Preston! ;)

Yes, if you can post pics, it would be appreciated! I tried scanning these knives; didn't turn out too well - the blade reflects all the light, you can't see the transition surfaces... :(

OK! Here's a crappy Chinese digi-cam pic of 4 knives; the two two-dots, and two new unused...you can sort of make out the transitions, especially on the 112...

(It's a big pic, so I'm only posting it, not linking)... :D
 
Mike, that is a nice 112, so clean looking with the micarta, no nail nick. Went through and viewed the rest of the knives...those are great looking:thumbup:. Preston

Chickentrax,
Here is a link to the 112 I was referring to.

Thank You! ;)

That does look like what these two I have look like...Hmmmm...It says 2288x1712 pixels but I can only pick up 480x359... :confused:

In that case, I'll try power-3M'ing this blade and see how it looks...
 
My 110 that I purchased in 1976, as well as two 2-dot and one 3-dot 112s that I have purchased, have not had sharp transitions between the hollow grind and the flat part of the blade near the spine. The transition is smoothed over.
 
I've now got a few 2-dots, including one that's NIB, and they all have smooth transitions and a finer finish than the new 110s.
 
Those older 110/112's will have a one finish look to them. The line between the backbone and the hollowgrind will be radiussed to the point to where you can't tell exactly where it begins. Current production knives do have a as ground finish on the hollowgrind so that is why you get such a crisp line at the top of the hollow.
Hope this helps,
 
Joe ... is the difference because of manufacturing differences (like grinding by hand in the old days vs. CNC today), or just a cosmetic thing you guys decided to change?

please correct me also if i am wrong but
did'nt the older blades hae much more hand work and finshing then newer blades...?
this amount of hand finisheing did it not also account for a longer camfer and cut to the point/clip?
 


Chickentrax...it has taken me awhile to figure out the ins and outs of getting the picture to this point, still need to work on the photos. I really don't know if this will work or help you now.

These are the two two dots that I spoke of in the above thread, one is mint(right one) the other(left) used and "refurbished" by me. You can see that the transition is smooth and the satin finish. Also the length of the clip on the one on the left is as you spoke about...longer. It is a two pin model of the two dot the other is a three pin. Hope this isn't to little to late. Preston

Thanks for the photos! :D

That one on the left has a much more pronounced chamfer than any [which is not all that many] I've seen (even among the "long" ones), and the "clip" is much straighter...definately unique... :)
 
The top two may be what you are talking about. Sorry for poor pic quality

Top one is a 112/, 2nd one is a two dot, third one is also similar and is a no dot, 2 pin, inverted micarta with a brass spacer. If this is what you are talking about.

I think I've got a handle on what the blade finish should look like now...I think a 3M burnishing disk will produce the same finish, or pretty close...

Looking at yours, I just noticed that *my* three-pin two-dot 112 has no nail nick either... :confused:

Someone on the assembly line must have broken the dovetail cutter that day... :D
