Abstract
A rotary-blade cutting apparatus which includes a spring-biased cutting-blade cover. The cover is spring biased to a closed position and includes a projection for manually applying a hold-open force to rotate and hold the spring-biased cover in an open or retracted position in a cutting-blade chassis. The handle of the apparatus is angled to provide for a more comfortable grip.
Claims11
A rotary-blade cutting apparatus comprising:
- a combination cutting-blade chassis and handle, said chassis further comprising a discrete thumb pad or indentation formed in a top right corner side of said chassis;
- a cutting blade rotatable coupled to said cutting-blade chassis, said handle being angled with respect to the plane of said cutting blade and one side of said handle forming an obtuse angle with a corresponding side of said cutting-blade chassis;
- and,
- a spring-biased cutting-blade cover, which is spring biased to a closed position and which includes a projection for manually applying a hold-open force to rotate and hold the spring-biased cover in an open or retracted position in the cutting-blade chassis.

A rotary-blade cutting apparatus comprising:
- a combination cutting-blade chassis and handle;
- a cutting blade rotatable coupled to said cutting-blade chassis;
- and,
- a spring-biased cutting-blade cover, which is spring biased to a closed position and which includes a projection for manually applying a hold-open force to rotate and hold the spring-biased cover in an open or retracted position in the cutting-blade chassis, said cutting blade chassis having an arc-shaped groove formed therein having an arch length wherein the arc-shaped groove is dimensioned to receive and slide therethrough the projection to an end of the arch length to rotate the cover to the retracted or the open position in the chassis.
