Dutch knife, 18th century? Amsterdam?

[Vantlicht]

I spent one hour to find the hallmarks on this knife :) Finally I saw the dog and found the hallmarks.
In my opinion it looks like makershallmark TP and below it you can see the andreascrosses of Amsterdam.
Am I correct? Like to hear it.

Perhaps I.P for Johannes van der Pels, registered in Amsterdam, 1784-1801, born in 1755, died in 1801
