As Steve says definatly bone. Nice shape to it. 1920s to 50s... 99.95 % of Victorian kukris dont have buttcaps.
Makes a change to see that seller marketing a kukri without fake ww2 or Regimental markings added .{can provide numerous past examples his sold in last 2 years.}
Perhaps the "kukri Fakes" article on sword forum struck home.... {Or various IKRHS articles about his past sales.}
Good that he will earn the same money for an unaltered piece.
Helps the learning.
