Challenger offers superior knife-grinding performance and versatility at a very economical price.

Straight knife edges and efficient cutting are the result of Challenger’s vertical-spindle, traveling-head design. The speed of the carriage is infinitely adjustable, permitting grinding of various styles of knives to your requirements. Stock can be rapidly removed, leaving a fine, precise finish. With the variable rate downfeed and rapid traverse features, fast easy loading of knives is sure to please you. The downfeed and traverse features will also operate in the manual mode by flipping the switch on the control panel.

The Challenger is built with very few wear parts, for virtually maintenance-free performance. In fact, you’ll never need to lubricate or repack bearings. The result is increased productivity, with reduced downtime.

Challenger’s low price and minimum initial investment make this knife grinder perfect for sawmills and grinding shops.
