I still see a lot of hewing being done in Japan.  
Almost every carpenter owns a Hewing Axe or hatchet, called a Masakari.  These
show up on ebay all the time, some new (they are still being made), often used.
Here is an example listing (not my listing).203996767809

These types of axe are common (on ebay) in the 16" (400mm) handle length, with a
5" (125mm) cutting edge.  I own several, some with long handles and larger
blades.
Below is a Tokyo tool shop I have had great luck with, and a hewing axe in
stock.  He may also have adzes, chouna in Japanese.

At 250 monme (a monme is 3.75 grams) this is a good weight, and with the long
handle you let the tool do the work.  "White paper steel" is basically iron and
carbon, and takes a keen edge.  The steel mills used to wrap the bundle with
colored paper, high carbon was white, alloy steel was blue, medium carbon steel
was yellow.
The prices outside Japan are great right now, about 130¥/$1.  So excluding
shipping this is $97 or £80.  Shipping is likely $45 FedEx
