If it's just linseed oil and beeswax, why not just use BLO at half the price? If you wanted beeswax too, that's easy to apply on top, and also cheap.
BLO as you might usually find it at hardware stores, etc is full of metallic driers and additives that are decidedly not food safe (They put it in so it dries and cures quickly , in as little as 18 hours)
Raw Linseed oil can take months to dry and longer to fully cure (I know, I still have a jar from grandpa's farm that has been laying around since the 1970's, if not older)
The Tried and True stuff is a polymerized linseed oil - That is; it is actually "boiled" - but not technically boiling - it is raw linseed heated to just below the boiling point - I think it was 175 degrees, I seem to remember reading - and maintained at that temperature for a set amount of time (I think an hour or maybe two, can't remember but details can be googled, I am sure), It dries and cures far faster than raw oil, but not as fast as BLO from the hardware store, but it is still pure linseed oil.
It is possible to make your own pure boiled linseed oil but I would not recommend trying it unless you have an outdoor location and you can get precise heat control (if it actually boils and gets exposed to open flame, you got a nice oily explosion plus burns on whatever body parts it comes in contact with as a result and If you don't get it hot enough, it won't polymerize)
So, given the purity of it (which you can just wipe on bare handed with no worries of "dangerous" chemical exposure) and the relative difficulty of making it from Raw Linseed, I think it is well worth the 40 bucks a pint or so. (and considering you need to use so little of it, a pint can last a year or two.. I'm still on my original pint can after a couple hundred wood bowls finished with it... ) I liked it so much I also got a can of their Varnish (Linseed oil & Pine Resin) and likely will get myself a can of their "Danish Oil" which is just plain polymerized linseed.
