    I've been very excited to have our own line of custom-manufactured stones produced for us, and this thread will serve both as an introduction and a place for discussing plans and progress as we roll models out. We're proud to be partnering with an experienced American manufacturer for the production of these stones.

    The <BYX•CO> philosophy and approach to sharpening stones is distinctly different from other companies. While most companies will produce one stone in multiple grits, edges are not the same thing as a surface finish on metal or wood, and simply progressing in grits isn't always what you want to do to get the best results. Edges optimized for slicing are different from those optimized for push-cutting, and then there's the full range of balance in between. Then there are the differences between setting a bevel, ironing out dings or chips, simple touch-up honing, etc. etc., all of which do best with different sorts of stones or progressions of stones.

    To top this off, the way a stone performs is the result of a large number of variables, including the type of abrasive used, the grade of that abrasive (there are many different grades of each abrasive type), the size of the grains, the degree to which they protrude above the binding substrate, the ratio of grit to binder, the kind and hardness of the bond, and so on and so forth. The problem is, companies tend not to bother with disclosing any of this information, and partly because it's a heck of a lot of variables to list out.

    What we aim to do with the <BYX•CO> line of stones is simplify that process with targeted stones carefully formulated for specific ranges of applications, and for each unique blend to be given a series name as a shorthand identifier. Our first stone in production is a canoe-shaped scythe stone in the Arctic Fox series. The Arctic Fox blend is a fast-cutting fine stone made with synthetic 400 grit blue sapphires in a ceramic medium-hard bond, and all single grit stones in the Arctic Fox series will be that blend. We have upcoming dual grit Arctic Fox series stones in axe pucks, 3" pocket stones, and 6" field stones in which the fine blue side is paired with a 240 grit grey coarse side. The blue fine side of these stones is slightly modified from the single grit blend to even out shrinkage rates between the two faces when firing, and results in the fine side cutting a little slower but leaving an even finer finish. All dual grit Arctic Fox stones will be in that combination.

    It leaves a finish and edge like you'd expect from a 1000-1200 grit stone, and with an aggressive "tacky" edge in slicing while still push-cutting well. It readily absorbs and holds water as a thin film on the surface of the stone, unlike some stones that will feel almost dry to the touch on the surface even when fully saturated, and the stone is hard enough that you can use it for edge-leading finishing strokes.

    Coming soon we'll be releasing 8" bench stones in the American Mutt series, which are an extra-extra-coarse stone of rather unusual character. Our manufacturer uses a diamond grinding wheel for dressing the mounted grinding points they also manufacture, and they end up with a large amount of loose grit in varying grain size in both aluminum oxide and silicon carbide, with a trace amount of loose diamond grit as well. These stones are a product of that mixed grit, and cut so quickly that you quickly develop a "mud" made entirely of steel swarf on its surface. However, the inclusion of the finer grit in the mix causes it to leave a much finer surface finish on the resulting bevel than one would expect. We've been experimenting with some samples of the material and are very impressed with the performance. The best news? They'll be super affordable!

    We also have plans being drafted for blends under the Bull Thistle (ruby stones) and Manticore (black silicon carbide) series names, and will be announcing the particulars once we have things finalized with them. :)

    The Arctic Fox scythe stones have already become our top selling item, and we have some significant names interested in the upcoming axe pucks. We're able to wholesale these, and I think that we'll be sending a few industry heads spinning once we get things up to speed. These aren't your old man's "India" stones, nor are they your new-fangled synthetic Japanese water stones. They harken back to the days when different varieties of natural stones were prized for the unique properties that they imparted to an edge, and we're bottling those qualities and zapping 'em into synthetics with an electric arc furnace. :D

    I think you'll have fun with them both! I need to snap a photo of the crisp shavings those files make tomorrow--it's pretty incredible. :D

    I've been using my personal Arctic Fox stone for sharpening all of my regular knives and tools and I continue to be pretty amazed by it. I love the canoe-shaped scythe stones of all sorts for general sharpening tasks. Easy to use them like a bench stone or like a file, and you can tackle flat, convex, or even concave bevels with them. When I resharpen serrated hollow ground knives I touch up the single-bevel side using the curved edge of the stone.

    Received a couple of prototypes of the upcoming Arctic Fox series dual-grit axe puck, and while there will be a couple more minor manufacturing tweaks it's shaping up to be a very nice stone. Here's a sneak peek.

    It's a P-38 military can opener, but they work as strikers, too! Handy little things. :) Glad everything made it to you safe and sound.

    I know it' a P-38 - I have a "few" of them stashed here and there, including in my wallet.
    I also have a few P-51's & FRED tools laying around. (I like the larger handle)

    yeah - that's why i called it a folding ferro rod striker -- it's a good secondary use, along with flat-blade screwdriver for chicago screws.

    Definitely going to pick one of those pucks up, I misplaced my lansky puck and it is driving me crazy, yours looks like the fine side is a lot finer which will be super nice!

    An Estwing doing what it does best. And after chopping a hidden nail, it made for a good test of the Arctic Fox puck.

    I really like that framing axe. What a great example of a task specific tool. I think the reason I like task specific tools is that it gives me a reason to buy another one. You know how it goes.....honey I just had to have this tool to get that job done for you. :)

    Great pics for supplementing the commentary. Or maybe I should say great commentary for supplementing the pics.

    Just heard back from my guy in manufacturing and they've got the blend on the pucks all worked out so that both sides fire to the same size and give a good flat result. They had to send a mold out for heat treatment because without it they were having trouble stripping the stones from the mold, and they'll be running some tests with the treated mold today. Should know more by Monday.

    I just got one of the Arctic Fox scythe stones and sharpened a lot of blades with it this weekend.
    It really is an awesome cutting stone that leaves an excellent working edge.

    I was mostly sharpening SAK's but I did do one blade in s30v and it sharpened up just as easy.
    The only thing I noticed was that the stone was harder to clean after the s30v.
    I use Bar Keepers Friend and I really had to scrub it to get the metal off.

    I'm really looking forward to the puck and other additions to the sharpening line.

    We almost have everything sorted out. The experiment with the heat treated mold wasn't as successful as we'd hoped but we have a few other things to try. If things start looking like they'll take too long we'll have some done up like the prototypes while we continue to tinker with things, as I know a lot of folks would like to be able to get their hands on these in time for the holidays. The only thing we're trying to correct with it (very slightly tapered sides) doesn't affect performance and is a barely-noticeable cosmetic matter. Still a detail we'd like to take care of if possible, though.

    We just received our first shipment of our new American Mutt bench stones and I thought I'd post up some photos of a bit of work I did with one of my pre-production ones. They're a rather unique stone made of a mix of silicon carbide, aluminum oxide, and a little bit of diamond grit in mixed particle size. What results is an extra-extra-coarse stone perfect for ironing out damage or setting bevels that leaves a finer finish than one would expect for so coarse a stone. All of the "mud" seen here is steel swarf--not loosened grit from the stone! I've found it a very big time saver.

    @FortyTwoBlades my fiancé is going to be placing an order for my birthday coming up. I told her I want a Baryonyx Machete, an arctic fox stone with lightly softened edges, and your new puck. I do all my sharpening with DMT diamond stones but want to give your stuff a shot and I figured that arctic fox would be nice for machetes and that big beast you designed. Got anything else you'd recommend grabbing? Is that arctic fox gonna be good for sharpening/maintaining the BM? Be on the lookout for an order going to NJ! :)
