Yep... I got a 635 for Christmas and it did the same thing. I sent it back for warranty the first week of Jan and got it back in three weeks.

Hello,
I am very glad to hear that you are enjoying your new mini-Skirmish,
but I am sorry you are having problems with the blade hitting the spacer
and causing the edge to roll.
I realize that it is a new toy and you most likely don't want to part
with it, but we will be happy to fix it for you - it could a problem
that can be just adjusted or depending on what our techs discover the
blade may need to be replaced (along with any markings). We would
prefer to see it and have the opportunity to make sure that your knife
is just as you anticipated it to be. Please consider sending it on
into us for adjustment, we would like to remedy this for you!
For warranty service and/or repair, please send your knife to us,
postage paid, at the address below, Attn: Repair.
We ask that you include a short note letting us know what you would
like done with the knife, any problems or concerns and contact
information including your name, return address, and a phone number or
email address. We recommend that you send your knife without the
original box, as they are often damaged in transit and that you send
your knife insured, be it through the USPS, UPS or another company of
your choice.
Please feel free to contact us with any other questions or concerns.
Thank You
