I have two hand planes that require the mouths to be widened to accommodate Hock irons. I have read it is best to use a “safe edge file.” This meaning one with smooth sides. I have searched for these in the past and could not find anything that seemed as if it would fit the bill.
Any advice/help will be appreciated.
Thank you.

You could always grind a safe edge on one of your files.

The only safe edge files I’m familiar with are the auger files:,320,43072,43089,70693

Of course you could take a regular flat file to the grinder and make it a safe edge file.

Auger bit files are safe edge.

Look for Swiss pattern pillar files.

I can’t give a source on files with safe edges, but supposedly they are available in full size files. I’ve seen them in NOS at least.

Here’s a good source explaining the different cuts and how they correspond between American and Swiss pattern:

lwllms has the ones, pillar files. As Arminius says, auger bit files will have a safe edge, but a pillar file will be better suited to the task.
