Blade-protecting sheath for an ultrasonic cutting system

A protective system comprising:

• an ultrasonic cutting system including a power horn coupled to a cutting blade through a nut;
• and
• a blade-protecting sheath that protects the cutting blade when the ultrasonic cutting system is not in use and when the cutting blade is removed from the power horn, the blade-protecting sheath comprising:
• a main body having a first end and an opposite second end;
• at least one ergonomic recess formed in the main body, wherein the at least one ergonomic recess is configured to be gripped and grasped by an individual
• a blade-receiving channel formed through the first end;
• a nut-retention chamber connected to the blade-receiving channel, wherein the nut-retention chamber is defined by interior planar walls that receive and constrain the nut of the ultrasonic cutting system;
• a blade slot connected to the nut-retention chamber, wherein the cutting blade passes into the blade slot and is secured within a blade chamber, wherein the blade slot has a clearance height that is greater than a depth of the cutting blade, wherein the blade chamber is longer, wider, and deeper than the cutting blade, wherein the cutting blade is suspended within the blade chamber;
• and
• at least one magnet that magnetically couples the main body to the nut.

A protective system comprising:

• and
• a blade-protecting sheath that protects the cutting blade, the blade-protecting sheath comprising:
• a main body having a first end and an opposite second end, wherein each of the first end and the second end include a hexagonal outer perimeter that is complementary to an operative portion of a tool, wherein the operative portion of the tool is configured to conform to the hexagonal outer perimeter of each of the first end and the second end;
• at least one ergonomic recess formed in the main body, wherein the at least one ergonomic recess is configured to be gripped and grasped by an individual, wherein the at least one ergonomic recess comprises an inwardly-bowed arcuate surface and an outer textured surface;
• a blade-receiving channel formed through the first end;
• a nut-retention chamber connected to the blade-receiving channel, wherein the nut-retention chamber is defined by interior planar walls that receive and constrain the nut of the ultrasonic cutting system;
• at least one magnet that magnetically couples the main body to the nut;
• and
• opposed barrier blocks within the main body, wherein the opposed barrier blocks define a blade slot therebetween, wherein the blade slot has a clearance height that is greater than a depth of the cutting blade, wherein the blade slot connects to the nut-retention chamber, wherein the cutting blade is configured to pass into the blade slot and be secured within a blade chamber that is longer, wider, and deeper than the cutting blade, wherein the main body is configured to suspend the cutting blade within the blade chamber, wherein no portion of the cutting blade directly contacts any portion of the blade-protecting sheath when the cutting blade is secured within the blade chamber.
