I'd be tempted to head butt or eye gouge during a "hockey brawl"...assuming I could ice skate. ;-)
Dixie -
The rules of the game covering “fisticuffs” prohibit head butts and eye gouging as do the precepts of unwritten “fighting etiquette”.
This, of course, does not, mean that such actions never occur.
In 2005, Dale Purinton (New York Rangers) was suspended for ten games for gouging Colton Orr (Boston Bruins) during - of all things - an exhibition match. The gouge can clearly be seen from 0:37 below:
Back in the “old days”, enforcers (or anyone else…) could get away with fighting far dirtier than their counterparts can today as the scope of conduct considered “acceptable” by both players and officials was infinitely broader.
One of the first names routinely mentioned in any discussion of all-time hockey brawlers is that of Dave “The Hammer” Schultz. Schultz ranks among the most celebrated - or infamous - goons of the sport. The fact that he was the designated enforcer of the Flyers’ “Broad Street Bullies”-era teams whose aggressive and dirty play has passed into legend is quite significant in itself.
Schultz’s enthusiastic willingness to take no-holds-barred violence much further than anyone else set him apart from his contemporaries. Not only did he routinely head butt opponents - he also often grabbed their hair. Now, hair pulling may sound homo or girlish (which, of course, it is…) but it was actually more common during the 1970s than one may think - probably due in large part to the hairstyles of the period.
Schultz would resort to head butting opponents if he was getting the worst of it, as he did here against Terry O’Reilly of the Boston Bruins in 1976:
The video below shows Schultz putting the Rangers’ Dale Rolfe through the mincer back in 1974:
The clip amply illustrates Schultz’s “no respect” approach to fighting - he punches Rolfe before the latter is ready, grabs his hair and sticks in a head butt. Significantly, Rolfe was not a fighter yet Schultz nevertheless mercilessly kept belting his plainly helpless victim for far longer than his enforcer role necessitated.
By the way, sorry for diverting this discussion away from its intended subject of fight sports. But keep in mind that despite the persistent efforts to eradicate it from hockey, fighting remains a sanctioned part of the game therefore the inclusion of on ice knockouts legitimately warrants inclusion…
