I'm really pleased with the two Cheburkovs I own. I don't know about the earlier knives that
austonh
mentioned, but their current models offer an interesting variety of sizes and styles at prices way lower than Shirogorov. (BTW, I'm a big fan of Shiros and own 6.)
I bought my Scout over a year ago and
posted a review here last year using my F95T as a comparable as it's a knife that many are familiar with. The Scout is solid, features premium materials, has excellent action, nice detailing, came very sharp, and feels great in hand.
Last fall I purchased a Strizh (Swift), mine being the smaller of the two sizes available. That knife is a thumb stud opener, "linerless liner lock" in CF--very light, wicked smooth, disappears in pocket, and came with a stupidly sharp Vanadis 8 blade. It makes a great gentleman's carry and a very credible EDC for those who like a small-to-midsize, lighter knife. Here's my Strizh next to my NeOn UL for comparison's sake.
For sure Cheburkov has no marketing outlet in this country at this point. It wasn't all that many years ago that Shirogorovs were really hard to find and buy here in the US. Shiro actually has only one authorized dealer worldwide, that being the CA-based company (not a supporting dealer here). The Workshop sells to the rest world directly, but North American authorized purchases can only come through the CA dealer.
A little Googling will reveal one German firm and one Finnish that are authorized Cheburkov dealers. I bought both mine from the German firm, they were easy to deal with by email in English, and both transactions went very smoothly. The Finnish firm offers a broad selection of Cheburkovs, has excellent prices, fast free shipping, and their site is easily navigable and understood for English-only speakers.
Like Shiro, Cheburkov will also sell directly from their Workshop. While it's true that they're not English-speaking per se, I've been able to email back-and-forth with Alexander Cheburkov and he's had my messages and his responses translated at his end. We've had some cordial communication to the extent that I've been able to order a custom build from him of his Raven (Voron) model, made to my specs at what I think is a very affordable price for such a quality, made-to-order piece. Think Spyderco Military for size and blade (actually bigger), but a Russian tip-up flipper in M390 and red C-Tek. Like this one without the Damascus.
