Handle assembly system for a hand tool

A handle assembly system comprising:

• first and second handle sections intended to be assembled with one another, the first handle section having a first cross-sectional radius and comprising a first end bearing surface to define a first bearing abutment and the second handle section comprising a second end bearing surface to define a second bearing abutment;
• threads provided on the first handle section complementary to threads provided on the second handle section that, when engaged, retain one of the first and second handle sections in the other of the first and second handle sections;
• and
• a friction seal interposed between the first and second handle sections to secure an assembly of the first and second handle sections, wherein when the threads are completely engaged, the first hearing abutment contacts the second bearing abutment, wherein the first handle section comprises a bearing surface, having a reduced cross-sectional radius with respect to the first cross-sectional radius, that extends longitudinally over a predetermined length of a void of the first handle section, wherein the friction seal is crushed predominantly radially by the bearing surface of the first handle section against the second handle section, when the threads of the first handle section and the threads of the second handle section are completely engaged, wherein the second handle section comprises an annular groove for receiving the friction seal and formed on an outer lateral wall of the second handle section, wherein when the threads of the first handle section and the threads of the second handle section are completely engaged the bearing surface of the first handle section extends facing the annular groove and the friction seal is crushed into the annular groove by bearing of the beating. surface of the first handle section.
