What to use on two weeks of growth......

[Roscotanna]

I'd use clippers then an open comb of any sort. I'd maybe only do a 2 pass shave to keep it comfortable after being tugged around by the clippers and stuff

 

[Ferry-shave]

I had several weeks growth and tried the iKon slant, with a Gillette Silver Blue - very efficient shave with the slant, no issues. I appreciate that YMMV.

All the best,

Chris
