Is this Benchmade BALI-SONG authentic? No model or USA stamp

Hello,

I recently acquired this Benchmade BALI-SONG.

However, I noticed that the blade only has the butterfly logo with “BALI-SONG” and no model number or “USA” stamp on either side.

There are no additional tang stamps visible.

The blade finish looks slightly rough, and the pivot area machining does not seem very refined compared to what I’ve seen online.

I have attached close-up photos of the blade and tang area.

Could anyone help determine whether this might be authentic or a clone?

Any insight would be greatly appreciated.

Thank you.
