New player looking for advice for TC Knife and just general game advice

[KinoWarlord]

Hello everyone, as I have stated any and all advice like how much to level a skill unless you're doing X build that kind of thing just for future reference. Lastly, any pointers how to level/build a Knife with TC would be appreciated like gear, points and whatnot.
Anything at all would be appreciated.

There are plenty of guides already, in short
1. Damage dealing skills should always be at maximum
2. Hacking. lockpicking - 135 of effective skill, there are lot of items that boosts those skills
3. Pickpocketing 105, there are some oddities that can be only pickpocketed
4. Mercantile - 105 effective, special merchandise is much better than usual stock
5. Don't overinvest in stealth, you can always get about ~140 of this skill from items(provided that you can craft them)

If you are trying domination - there is my build for chemguns few topics below, it starts as knife user and I share few advices about how to start the game.
There are also build planners, it is better to plan what feats you will take in advance, this is the updated version with new feats
