Why "Dull 'Hawk"?

People seem to really enjoy using my "Dull 'Hawk" moniker (often shortened to "dullhawk" online) as an insult. The "dull" part, anyway. I'm sure I've explained this before, but I can't find it, so I suppose it's appropriate to post it here.

Dull 'Hawk is my "mountainman name", and is short for "Dull Tomahawk". (We mountainmen usually call our tomahawks "'hawks" among ourselves.)

So, why is my 'hawk dull? Actually, it isn't. Back in 1992 I was at a mountainman rendezvous and was competing in the tomahawk-throwing competition. My tomahawk would hit the target every time... and fall off. In practice it stuck every single time, but in the contest it simply refused. Performance anxiety, I suppose.

Anyway, people gave me the name "Dull 'Hawk" at that rendezvous and I kept it.
