Victorinox Venture Pro 6mm Sharpening Rod Adapter

The hole for the sharpening rod is 6.3mm. I don't have these 6mm rods to test how well they fit. Please comment on this design if the tolerance to too large/small. I will change the design based on feedback.

Unfortunately 5/16" (~8mm) diameter sharpening rods are too large to use the same type of adapter. Such an adapter would need to be bulkier to offset the rod out of the sheath slots. 

I got this idea from Felix Immler. See his video here:
