Does anyone have real use experiences using the Buck 639 Fieldmate serrations? Wondering how they preform when cutting through thin sheet metal? (Id imagine that was there Orginal intended use, as most serrations are made for and not wood cutting)
 
Why would someone use a field knife to cut through sheet metal? There are better options for that. Just curious. Serrations also work well for cord and rope, don't they?

For instance.. the Randall 18 serrations were purposely designed to help a downed Huey pilot cut himself free of a crashed landing in Vietnam.in a package he can carry on his belt as well as hold survival supplies in the handle. With the looks of the field mate serrations, they do not appear made for cutting wood due to the spacing of the teeth.. I could see if they were sawteeth and closer together.

help to saw through softer aluminum, not steel sheet metal though.

might work though with minor damage to the sawback. depends how thick what gauge the sheet metal is?
 
Ah, thank you Jesse! A little early up here... need coffee.
easy to confuse. I read serrations and wasnt thinking how the 639 had a saw back even though he said 639. so i thought same thing, but I got to see his other post you didn't, with the randall. then remembered the 639 and figured it out.
 
For reference...
