Amici,
Marbles products have been manufactured in China since the late 1990's, so unless you're lucky to have come across some old stock thanks again to NAFTA and Bill Clinton you have a Chicom tool..
On the other hand, they do use a decent grade of carbon steel in their axe heads so edge retention is not really an issue, but it seems that their earlier products weren't thought out or tested completely so they do come with some stigma attached.
As I mentioned in an earlier post, Marbles products seem to get a regular drubbing in various online forums and deservingly so, although in the last few years their quality has getting better. It seems that anything coming from China nowadays because of their odd tendency of just making and sending it out without any R&D or QC has helped them in being labeled as crap.
As for any axe/hatchet that's not made in the Nordic countries, I would sand down the handle and remove the varnish completely and as mentioned earlier then rub down the tool with liberal amounts of linseed oil and you'll be good to go..
By removing the varnish and using linseed oil, you'll notice the increase in your slide and swing when using the tool.
Cheers,
Serge
