This knife has a 3/4 inch (19 mm) carbide tip welded to a 5/16 inch (8 mm) quick change holder. It can also be purchased with a regular chrome tip (200-KNF-0810).

For proper seed placement this opener should be used in conjunction with the 300 series seed boot system using attachment 300-ATM-1035.

Replacement weld-on tips are available for this product. 410-TIP-0801 is the replacement carbide tip for the 200-KNF-0811 and the 410-TIP-0800 is the replacement chrome tip for the 200-KNF-0810.

Driver 400-DRV-1010 should be used to protect the tip when installing this knife on the quick change adapter.
