I wouldn't be surprised if you got one that is sharp and one that is more moderate. That doesn't mean they are ground to different specifications or that someone else will get the same experience ordering the same products.Compared to the blade of the Tatra Platino I found the Tatara blade less forgiving, it requires respect otherwise with some razors that expose the blade more if you are not careful there is a risk of getting many cuts.
The Tatra platinum blade is gentler as @cranewarrior wrote quite smooth.
For me Tatra platinum is not the same blade Tatara,completely different.
Of the Tiger platinum blade I don't know, I have never found it.
Next week I would like to try the Tiger stainless blade, in the past few days I found out that there are many Tiger lovers here and I would like to understand if it really is the Tiger stainless blade is a bad blade as @lasta writes.
I hope we will survive.
It could be batch variation. It could be One dulled on its way from the factory to your shave den.
Test with chart.
They seem to be made to the same specification to me.
I need to test another Tiger Pt at some point, because some people said they got one that was as sharp as the Tatra.
