Chinte (珍手) - "Rare (extraordinary) Hand" ("Редкая (выдающаяся) рука"). Sometimes translated also as "Strange Hand" ("Странная рука") or "Unusual Hand" ("Необычная рука").
Chinte is believed to be a Shuri Te kata. Funakoshi Gichin Sensei tried to rename this kata as Shôin, but the new name didn't stay.
Chinte features unusual hand techniques (which explain the name of the kata) and only one kick.
And, yes! Three hops at the end! I have seen three explanations:
1) three hops are the traces of some lost techniques;
2) the application is holding an opponent's arm and moving back to break his wrist (I will show this application during the training);
3) these three hops were added in order to return to a starting point (this one sounds strange to me).
