Commentary
UEW reconstructs Proto-Ugric *e, but this is an erroneous choice, as Hungarian e points to Proto-Ugric/Proto-Uralic *ä, and this would yield *ǟ in both Khanty and Mansi regularly. So the reconstruction of UEW is erroneous, but the Ugric etymology is phonologically plausible. Also semantically the etymology seems possible: the meaning of the Mansi word is quite specific, but the reconstruction meaning 'unpick' would fit all the Ugric cognates.
The word is scarcely attested in Ob-Ugric, and it is unclear whether the Khanty and Mansi words are real cognates or whether we are dealing with an internal borrowing within Ob-Ugric. However, it seems possible to reconstruct Proto-Ugric *päjV-.
Conclusion
A Proto-Ugric word can be reconstructed, as the cognates are phonologically regular and semantically plausible.
