That is a very risky technique - cutters apply a very large and
uncontrolled force which can easily tear up the solder pads.
It is much safer to melt the solder at both ends of the resistor,
swapping quickly between one end and the other, until the resistor
gently slides off.
(Also a query about the resistor value: does it truly have to be 13K?
Is this potential divider so critical that it cannot use one of the
readily available standard values of 15K, 12K or even 10K?)
