What kind of knife is this?

[PhoulPlae]

I have an interest in serrated back knives, and this one caught my eye. I know, its only the tip of the blade, but I haven't seen any knives with a serrated spine like this one.

A " no longer made" Buck Field Mate, 5.5" blade, moulded rubber handle, and serated clip. Wish they had made the damn things without the serations!

Thanks. So only the clip is serrated, not the whole spine?

The spine has a sawback. The Buck model 639 looks like a downsized version of the Buck 184 Buckmaster.
