Irregardless of the type of sword that you build, it may be part of your costume and needs to go where you go. If this is so then you will need a safe alternative.
This sword is made from pine slats , it is not sharp but still looks real from a distance.
You will need a Drum/Belt sander. (quick shaping, hand shaping will take a relatively long time.)
Pine Slats. (local HD sells for $12 for 25)
Spray Paint, Primer, silver, gold
Electrical tape, I used red
The total build not counting the drying time was less than an hour.
Step 1: Shape the wood
The Slat chosen was from HD. It is 1.5 inches wide, .25 inches thick and 48 inches long.
shape the slat on a belt sander. This is the quickest way.
