This information about Queen changing the source and type of their ACSB, I find extremely disturbing. I hope this is not some ill conceived cost-cutting measure but perhaps their original source is no longer in business? As others have noted, it is an extremely attractive scale choice, rich in colour and nicely jigged. You mate this with some fine patterns and D2 choice and you have an excellent range. Compromising that, you could be holing the company under the water-line. I really hope not as many, many of my cherished knives are Queen Cutlery and the ACSB and the earlier WCSB scales are wonderful materials. I have a 48 Whittler in the WCSB (so I suppose it must be about 10 years old?) and it's a magnificent knife. No gaps, strong W&T and smooth action, even arrived sharp so keeping it that way is no chore. The best bet seems to be to look for ACSB knives (or BEM if you like it, I don't) and pre 2010, still some excellent bargains to be had and they are new/old.
But, the OP asked for new era Queen knives in particular. Well, this arrived last week to my European door, after quite a lengthy wait. Pattern No.21 Mini Muskrat in Black Bone with the Keystone (pinned) shield 3.25" with brushed stainless blades which I feel are a lot nicer than some of the oddly over polished buffed to death 'molten look' which you can see on many recent Queen stainless knives.
Good points: first-rate snap and opening action (much better than on the Northwoods Norfolk which is very tame). No blade rub, v.good on a single-spring knife. No blade play either. Generally good radiusing, well matched scales, proper fitting to bolsters.
Bad points: some gaps and a gap between scale and liner which is not pleasant. I can say that this is the bluntest knife I've ever received, you could probably lick it in all safety! Nor does it seem to want to sharpen up much either, this is sinister.
Overall an interesting compact knife and a good effort, so this bodes well if only they had the manners to send out a knife with something like and edge....
I was given a 2013 Scout knife similar to ones already shown and I'm afraid that this knife does not impress me at all. Raised springs, very weak looking punch and can opener (I think they'd break) rough cheap feel to it and I'm unabashed in saying the RR equivalent is as good or better.
But, the Mini Muskrat is nice. Let's hope I can get an edge on it!
