remember the handles have some thick cheap lacquer on them that is semi transparent ..... it will have to be stripped off as well before you can refinish the handles.
I used Kwik Strip as well on the heads, then blued them with some Birchwood Casy Cold Blue....they looked fantastic imho
Handles got stripped with Citristrip then hand sanded and blow torched, re hand sanded, stained, sealed, then leather wrapped the bottom 1/3ish of the handle with some thin leather straps I buy cheap from a supplier I will link below, I buy ALOT of their leather straps and use them on all kinds of projects...
wet the leather, that gives it just a touch of stretch so that when it dries, it holds very tight. use Firbang's leather dye on it to color... wrap the handle, and attach it however you prefer. Personally I use small black cut carpet tacks... they look very...... traditional..... to make the attachment top and bottom, then wrap the top and bottom section with about 1 inch of jute twine dipped in epoxy so that it makes a good bond. ( drill pilot holes for the tacks with your very small drill bit to keep the kiln dried handle from splitting, just a very small hole, not very deep )
end result looks great and holds up to the toughest abuse I've been able to throw at it yet.
This is the supplier for the straps.... you'll find a thousand or more uses for them.... buy em thick, thin, 1 inch wide, 3 inches wide.... just, handy stuff to have around...
The 3 and 4 inch wide ones make awesome instant sheaths for knives by simply cutting to length, folding the top into a belt loop, and stitching the sides together.

6 inch blade, cut the strap off at 18 inches.... fold the first 6 up onto the second 6, then fold the back 6 inch ear in half.... drill some holes with a thin drill bit, and sew it all together with some bank line.... takes like 10 minutes, quality leather sheath for a couple bucks..... /shrug, works for me!
FYI, I like the 3/4 inch or 1 inch for handle wraps...in a 3/4oz weight so it does not add too much width and bulk and is easier to work with.... YMMV
pics of the wrap before I twine wrapped the ends....
Once the edges are re sharpened, and the cold blue is taken off the cutting edge, and the twine wraps are done....they look really good.... I'm up to.....5 or 6 now I think, counting the Cold Steel Warhammer as well.... that top axe is a Rinaldi and its a beast!
I kinda went thru a Viking phase LOL....
