Where did TOPS get its start? The Steel Eagle series of knives were the first models ever created by TOPS. Over many continual years in the field, in every terrain and in all conditions, the Steel Eagles have proven their strength, durability, versatility and dependability within the Special Operations community and with civilians as well. The Steel Eagle 107E is a quarter inch thick 7 inch blade for those who prefer to have theirs without the saw back, and it continues to be a favorite personal carry choice of the quiet professionals. Included a black ballistic nylon sheath.
