Fixing blade play on a Schrade 340t?

[Frostyfingers]

So I found a great bargain on a 340t this week at an antique store. Someone apparently thought it was only worth ten bucks as it was blackened and covered with what appeared to be melted wax. A little cleaning, and she's good as new! The only thing wrong is a little play in the main blade. My question is this: can I fix the blade play? I've done this on other slipjoints by pinching the bolster gently in a vice...good idea with the Schrade? Is there another method, or should I just get over it? (the play really isn't bad, and it was a steal even with he issue)

Thanks,

Frosty
