125 Year Anniversary is a version of the popular Basic 511. Done in special colors to celebrate 125 years of knife making. I think it's quite attractive, and you aren't likely to lose this one in the grass either. The carbon steel blade about 3 5/8" long, 3/4" wide, and .080" thick.The knife weighs about 2 3/4 ounces, or 3 3/4 ounces in the sheath.
