Translation of knifer in German

Of course I have already tried, but it did not work. I will try it again. Meanwhile, here is the reason for my short emails... only one hand free at a time, see explanation in the image of me.
In South American we speak normal Spanish, but sometimes it sounds like music and not as you are used to it from the school books and video tutorials from the language schools that you have learned in Guatemala.
No matter then. I wanted to study Spanish for years now, because you know, it really helps? And how long have you been learning Spanish? Please write me soon. Best wishes. Your Alfi.
