I guess if you have the feat to spend on it "Quickdraw" and carrying multiple bows is the answer.
If opponant attempts to strike weapon he opens himself ot AoO. By dropping bow and drawing sword (free actions) the opponant is potentially struck and now does not have the bow to sunder.
A 5'ft, a new bow, a cry for assistance because your running out of bows, and hopefully the sword slinging bastard is down.
That aside the swordsman still has to surpass the to hit roll of the Archer. So its not the given that everyone make it out to be.
And as his attempts miss the Archer is taking his 5' step and center massing a collection of arrows in the swordsman.
How much does damage does the swordsman want to take to chop a bow that is to be replaced with flying axes or daggers or even a sword itself.
It could be an out of the frying pan into the fire situation.
And as far as why the spiked gauntlet? Not everyone has a feat to use on quickdraw at the lower levels.
