Are any mods transferred from the off-hand claw when Kicking or using the Blade skills?
Unfortunately, none of the above mods (including leech, elemental damage, and Crushing Blow, among the other mods) from the previous FAQ are transferred to Kicks or the Blade skills (if they are on the off-hand claw). Only “indirect” mods such as +skills, +stats, resists with off-hand claws. Do note that this claw order (between the main and off-hand claw) is reset after you gain a level or take a Town Portal/Waypoint, so remember to re-equip your claws after these events. Note: As stated above, Shields tack on effects the above effects on their listed normally, if they have they possess the proper mods (e.g.. OW on SwordBack Hold works on BF and Kicks).
