Both N13 and N17 knives are offered either hardfaced on one side, or with an alloy casting and an optional cast alloy pipe protector. Regardless of the soil conditions, there's an N13 or N17 for most any situation. These knives are made from 3/8" steel and are punched with 1/2" holes for 1-1/2" to 3" centers.

Nichols N19 knives are available standard, hardfaced on one or both sides, or even with a chrome alloy wear edge with an optional chrome alloy pipe protector. The N19 is one of Nichols' best selling knives and has a reputation for being the finest in the field. The hardfacing on these knives is applied by hand with acetylene, meaning it's the smoothest hardfacing available which makes the N19 self-sharpening. These knives are 19", punched with 1/2" holes for 1-1/2" to 3" centers and are fabricated from 1/2" material.
Backswept Knives for Dry Fertilizer Delivery
| Style | Part Number | Weight (lbs) |
| 1-1/2" Tube | N13HF-112 | 3.8 |
Modeled after the other N13 knives, this Nichols knife is made for the delivery of dry fertilizer. Constructed from 3/8" by 2" steel, this knife is harfaced on one side to keep it sharp. This N13 is also equipped with a much larger 1-1/2" tube necessary for the application of dry fertilizers.
