• the abovementioned bevels or chamfers may optionally only be provided on the shoulder 52, or on the edge of the orifice 31.
• the corresponding shock is obtained just before the contact between the front face 57 of the hammer 42 and the rear face 35 of the annular partition 30 (the dimensions of the rod 47 and the blind bore 60 are adapted accordingly).
• the operator wishes to reactivate the knife 1 for the application of a new shock, it limits or eliminates the pressure force on the front end 10 of the blade 2; the return spring 41 then pushes the trigger member 40 forwards, causing the blade 2 to be extracted with its support 13.
• the free end face 48 of the rod 47 is extracted from the blind bore 60 of the hammer 42; it is automatically decentered by the decentering means 41, 44, 49 (coming in lateral support against the lateral wall of the orifice 31), and it resumes its guard i with respect to the front face 57 of the hammer 42, in position for the application of a new shock or cycle of use.
• spiral spring 43 is advantageously chosen relatively powerful to obtain an effective shock; on its side, the spring 41 does not require as much power and is therefore chosen lower, simply adapted to bring the blade 2 and the trigger member 40 to the maximum extraction position.
• Such a knife structure 1 optimizes the application of a shock to facilitate the opening of bi-valve shells, especially oysters.
