Here's my Moore Maker collection in its entirety.
The large stockman with Delrin handles and a punch on the bottom is of recent manufacture, but neither the knife nor the box have a date. The tang stamp reads 3305. The box reads 3305B so I think its a Bear. It seems to be a well made knife. Good snap and no play in any of the blades. F&F is quite good with the exception that the main blade spring is slightly proud when closed. The Moore Maker stamp is quite small given the size of the tang. It is in a straight unarched line.
The smaller stockman is a 5300, has bone handles and was made in 2015. Its a very nice knife with solid snap, no blade play and excellent F&F. I believe it is a Queen. The Moore Maker tang stamped is arched.
The two lock backs are interesting. The mesquite one is a 5105MLB. The yellow bone one is a 5105ULB. The blades are different and so is the handle shape.
There is no date on the Mesquite. According to Moore Maker the mesquite one is a Bear. Oddly the gentleman from Moore Maker told me Bear was the only one that had ever made these for MM. Earlier in this thread it was mentioned that Canal Street had made some of these and it is almost identical to the Canal Street Pinch lockback. One difference is the CSC has a third pin at the butt end just like the yellow one above, but the mesquite only has two pins.
Here's a pic with a CSC Pinch. The blade shape and handle shape is identical between the mesquite and the CSC. The bolsters on the CSC are slightly more squared off and MM's are slightly tapered. They're really close. I don't know if MM owned the design, or if Bear bought the tooling from CSC.
In addition to the different blade and larger handles, the 5105ULB has brass liners while the other two are steel. Its dated 2013. Oddly the box bar code label says its a 5105ULb 2013 5" lockback. The 5105ULB and 2013 agree with the tang stamp, but is not 5". These are all 3.75" closed. I'm guessing the "U" might mean "Utica", but the "M" on the other one seems to indicate mesquite, so I don't know. The yellow one could be a Utica, a Bear, or maybe a Queen since it does have some really pretty yellow bone. Its got some blade play. Not too bad, but its there. Also, out of the box it had a place midway open where it got tight and very gritty. Flushing and oiling helped this tremendously. I think the f&f on the mesquite is better, but the yellow is a factory second so....The yellow one has a gator snap open and closed. If you aren't hanging on it will get away from you. Almost got one of my fingers the first time I closed it. I don't think I have any other knives with this strong of a snap.
One other thing I noticed is all the yellow knives have the same type of shield. Its smaller on the 5300, but the same design. Its flush with indented lettering.
The shield on the mesquite is proud and has raised lettering. I don't know how to tell if a shield is pinned of glued. I assume these are all glued.
They all seem like decently good knives.
One more pic just because.
