"The reason why they're not cut all the way through is because the bagels are propelled through a spinning blade and they're spit out at a very high velocity, and if they're cut all the way through- the tops and the bottoms would separate," Trust said.
If that were to happen, the two pieces of the bagel would go flying and need to be matched back up by the buzz saw operator, Trust said.
For Fineagle-A-Bagel, Trust said they used to make a three-quarter cuts for grocery wholesale, but have since decided to go with uncut bagels to avoid losing any freshness.
But Trust had a tip for those looking to have fresh cut bagels.
"Cut them all and freeze them, and then put them frozen directly in your toaster in the morning and they come out beautifully," Trust said.
