My humble advice is to try 2,3,4 or 5 blades (however which amount per blade brand), before moving on to the next blade (my one & only 'go-to holy grail' blade is Shark Super Chrome).
Also, long ago when I received my Sampler, I started a Thread entitled "In what Order should I test these Sampler Razor Blades?", and the best advice was from member Optometrist a.k.a David who stated;
"I say jump straight in with the Feathers [and then the KAI's]. Yes, they are sharp, but you learn very quickly to let the weight of the razor do the work for you. If you can get the feather right, then it's plain sailing with the others. A few nicks and cuts early on are nothing to worry about and stand you in good stead. Start with a lesser blade and it's a continual learning process as you step up the level of sharpness".
Also, member Npsarros stated, "Keep a spreadsheet with every shave [you], have taken, rating each blade as [you], go along". My spread data ratings reads in columns as follows;
a) Razor Blade / Country / Type
b) Sharpness? (aggressive, moderate sharpness, mild sharpness, tugging or pulling, ect...).
c) Closeness of Shave? (DFS, CCS, BBS, ect...).
d) Smoothness/Roughness of Shave? (moderately smooth, very smooth, very,very smooth, ect...).
e) Comfort of Shave? (no irratation, slight irratation, touch of burn, itching, ect...).
f) Overall Rating? (awesome, great, passable or unpleasant).
g) Compatible with your Razor(s)? (yes or no).
PM me with your e-mail address and I will send you my workable spread sheet example.
