A tool with 100/100 will get almost no degrades. A tool that has 99/100 will start causing degrades fast! I noticed tonight when I was trying to make Pebbles a blue heavy armor. As I am lazy, I have only heavy vest at 144, the others somewhere around lvl 103~109. Vest, perfect at once, same for pants and sleeves. Then my tool wore a point. Poof! took me about 10gloves, 10 boots and 15 helmets to get a ql150 on them.
Still dont get it but will keep a sharp eye on my tool when crafting will above my lvl and replace it every time it drops from 100 to 99, as the tool costs 1000 dappers and a degrade will cost me up to 200K as the ql34 item just cant be sold...
Factors that effect crafting result (no proven, but I have crafted a few items in my time

-Tool hps
-Mats over ql ... ql200 mats on a ql180 craft (better mats less fails, also now the % changes based on the mats used ... you get the ql150 success rate even if you use ql180 skill when you use ql150 mats)
-Grade of mats ... (seems that higher grade mats seem to reduce success rate) also degrade with excellent mats cause the item made to be entitled basic/fine/choice !!! stats of excellent, title of choice, junk to NPC

-Repeation ... I have found that if I get a run of bad crafts ... it stays like that bad, if I get a run of good crafts ... the results stay good! (There must be some logic in there ... random seed list not very random maybe)
-Equipment worn ... don't craft in anything other than light or Nakid


-Whats in you bag ... seems weight and bulk have some effect, but not much.
-Where you mats are ... seems this has and effect too

All of the above factors seem to have an effect, no much in isolation, but I guess they add up.
I personally get my best results out in the field! Dig-Craft-Dorp or Sell.
I tend to replace my tool regularly... as stated 1000 dapper to a crafter is money we wouldn't bend down to pick up

I find that crafting with mob mats has a high success rate (but this could be down to the basic vs choice grade thingy!)
Don't think location or weather has an effect, but making for order vs lvling does, but thats not a game mechanic thats just Sod and his laws!
