Step 1: Step 1: Supplies
The peices in the picture
Step 2: Step 2: The handle
take a yellow lego peice with 8 circles on it and put a flat yellow peice with 12 circles on it on top. then find some pole like lego peices for the handle.
Step 3: Step 3: The blade
Take 7 square black peices and 7 grey ones and an 8 dotted flat grey peice. stack the black peices and then the grey peices and put them next to each and put the flat grey peice on top of the 2 stacks.
Step 4: Step 4: The Blade part 2
for the top of the blade, take a grey diagnol peice and put it on top of the grey stack. Then put a 2 dotted grey peice next to it and 2 dotted black peice next to that. Then put another diagnol grey peice on top of the to grey peices and another 2 dotted black peice next to that. Finally put a diagnol black peice on top of the grey and black peice.
