To bych musel brusku rozebrat. Možná někdy.

Pokial je to urcene na brusenie noznic nozov 30min. je ok vyrobca netusil aka bude ina funkcia...

No to výrobce netušil😁 Předělal jsem brusku na značku DoDo (dodělej doma). A jsem celkem spokojený.
Ty nože by bruska zvládla brousit déle něž 30 minut, je tam malá styčná plocha. Ale několikacentimetrový achát je větší zátěž.

Medzi prestavku mozes vyuzit na kavicku, caj, cigaretku... 😃

Jenom na ten čaj😃 Na odpočinek rukou, některé kotouče už mám jeté tak, že vibrují. Navíc já se zabavím i jinak než broušením. Takže ty přestávky nevadí. V zimě na balkóně bruska chladne rychle😁 , horší je to v létě. Nechci ji zbytečně přetěžovat, protože výrobek používám určitě v rozporu s návodem.😃

Pokiaľ dodržuješ pravidelné prestávky a nepotrebuješ denne používať určite postačuje .
