Why consider this model?

  • Consider the current-reference US Model 445 for a hand-guided two-stage routine when its fixed, page-marked 20-degree-class straight-edge capability and kitchen or pocket/hunting knife use suit the task. The manufacturer also marks serrated use on the exact page, but its Model 445 manual does not explain a distinct serration method.

Tradeoffs to weigh

  • The Model 445 asks the user to control each blade stroke through fixed slots; it is not motorized or angle-adjustable. The product page's 20-degree capability does not say whether the angle is per side or included, and its serrated marker is not accompanied by a serration-specific sequence in the linked manual. The manual says not to sharpen scissors and states that spare parts are not available for this model. A separate leather strop, replacement-abrasive status, blade-clearance limit and seller-box contents are not established.
