New bolo - dahong palay & leather cleaning advice?

[wildwolberine]

New bolo! Kind of an impulse buy but I’m really pleased. Very similar to one i just posted (http://www.vikingsword.com/vb/showthread.php?t=28986). Xasterix kindly IDd that knife as a sinanbartolome profile from Laguna province, Luzon. Different maker’s mark (a “B” instead of a horizontal “P”), and the blade profile is more of a dahong palay?

Carabao hilt, through-tang (peened over), brass ferrule. There’s a tiny hole neatly drilled through the hilt, it must be for a lanyard as it couldn’t be insect damage). Leather sheath with attached belt. Thin, tapered blade. It does seem to have a chisel grind but it’s thin and hard to tell.

These are before-cleaning pics. Will clean the blade with WD-40 and 0000 steel wool and treat the horn with Hooflex. That’s duct tape residue on the leather. Any advice on removing it?

Age probably midcentury? Thanks!

Dimensions: 56 cm overall length, 41 cm by 4 cm blade.
