Sharpening a slot punch

[Hildebrand]

I recently received a slot punch but it is not anywhere near sharp. What do you guys use to sharpen punches like this?  It seems to have a good bevel in place. 

‘Thank you.

Have a look at this video by Ian Atkinson -- 'Renovating a Vintage Vergez Blanchard Crew (Oblong) Punch'

He uses a diamond plate, but any sharpening stone - oil, water/ceramic, or diamond would do the job, or just wet & dry paper on a sheet of glass or a ceramic tile

I used two needle files on the inside, one round rat-tail for the ends and a flat for the sides. I only gave the insides a bit of a wipe with them after I went round the outside with a flat diamond plate and some fine whetstones. The files were wiped over the inside lightly to remove any burr raised

Thanks for the info,I too have a few slot punches that are no where near sharp enough.
