Step 2: The Steps
Step 3: Last But Not Least
Step 4: Repair
ok...if you went out and threw it at something and the end was ruined, frayed, or splinterd...so did mine. all you need to do is resharpen it and BANG good as new.
Also, after a while the duck tape end might become nasty and gross, or be torn...i dont know all the posobilities. just cut off the old and redo the fin.
