If you have some plexiglass handy, try making your own. I placed a blade on the plexiglass, traced the outline and cut out the rough shape. Place the blade (curved side up) on a cookie sheet, then place the cut out plexiglass on the blade. Make sure it's lined up even with the blade. Pop it in the oven at LOW heat and watch for the plexiglass to melt around the blade. Too much heat will put bubbles in the plexi-blade. Take it out and sand the edges and drill your hole for the clevis or split ring. 1/16" thick plexi worked better for me but 1/8" will work as well. Hope this helps.
