yep, torx-TR is like torx, that silly nudge should prevent that a regular screwdriver can be used.
i think he needs to find out if it is millimeters or inches before he buys something? torx and other hexgonal often use anglo-saxon metrics when the product comes from US or UK. (motu, digitech, kurzweil... not apple.)
it is quite difficult to find those in germany for an appropriate price, not to speak of ukraine. i once bought mine in a weaponry shop(!), because 100% of the ebay offers were + 10 euro shipping from UK.
