That looks like a honey locust. Check the ground for long bean pods.
I had a look at some of the other pear trees. A few of them do have some spikes, but not like that. I will take a picture later. Also the pear branches are not very straight.
I have grafted to the ornamental pear in my yard as well, no issues to date.
I grafted Harrow Delight successfully to my bradford last year and i'm finishing it off with Bosc this year, no worries. :)

Is the Bosc scion on the Bradford or on the Harrow Delight?
