This was copied from Bill Bagwells book “Bowies, Big Knives, and the best of Battle Blades”.
I edited it down to just the technical stuff. There was a lot of extra fluff that made it two pages long and what can I say I’m a lazy typist LOL.
The Guard,
Cut the ends of the guard off at the point where top and bottom bend to make the “S” curve. Finish the ends off by filing, sanding, polishing.
The Blade,
Starting about 3/8 of an inch forward of the guard, the blade should be narrowed in progressive taper until it’s 1 7/8 inches wide at the point where the clip starts across the widest part of the cutting edge. You can use a file or a grinder but be careful not to overheat the blade.
The Point,
The point is carried to high and needs to be dropped. Using a File or bench grinder lower the point ½ inch. Do not overheat the blade if you use a grinder. The unaltered blade measured ~9.5 inches from the front of the guard to the point. The modified version should be ~9 inches long.
The clip,
The original W49 clip point is not sharp so using a file rough the profile and finish with you favorite sharpener.
The Handle,
Use a file to thin and round the sides and ridges of the handle until they feel comfortable to you. Spend some time here there is plenty of material to work with. Do not remove the handle hook.
He suggests performing the modifications in the above order.
I modified (Bagwellized) my carbon steel W49 following his directions and using only a file. It’s not difficult just takes a few hours. By the time, I got the handle scales thin enough to fit my fathers hands I had filed the head off the rivets. I picked up replacements and the counter boring drill here.

Good luck!
