how would you guys go about putting a 45 degree mitre on thin liner material

Attached is a link to what I am talking about. If you look at the liners closely you can see that HHH put a 45 where the bolster meets the liner on the main slab handle in order to give it a seemless look. How would you guys do this after gluing the liners together
