If its really sticky, Id send it in. I wouldnt worry about % of lock up unless theres blade play. Ive had 2 Sebenzas forever and they both lockup a little late, but no blade play. Whatever happens, they will take care of you. The whole CRK staff is a class act. I had to send one in, and I dealt with Mrs. Reeve by email and they are truly what customer service should be.
