Before I say anything, I like the general look, but I also see several picky little issues.
Thin stripes that bleed on the edges of printed materials are subject to trim problems. If the card isn’t trimmed exactly right, the stripes can get thicker, thinner or appear to be noticeably crooked.
I probably wouldn’t be inclined to space out your first name like you’ve done just for the sake of justifying it with your last name. It’s pushing the limits of it looking natural.
The typeface you’ve chosen for your name is a little clunky. I’d be inclined to stick with the Futura you’ve used elsewhere.
Why is there a thin red line in the word EDGE? (You won’t always be there to answer that question when people wonder about it.)
The kerning on your name and tagline needs quite a bit of work.
The round shapes at the top and bottom of the card probably ought to be round, otherwise they draw attention to their failure to be so.
The little pencil in the razor blade is an interesting idea, but it’s so small that I’m unsure if it will be legible once it’s printed. The thin lines in the pencil could easily fill in from dot gain.
Why are you using the Wordpress logo on the back of your card? I see no reason to draw attention to the company hosting your website.
I’d kern the space between the two slashes in https://
Finally, I’m not so sure the razor analogy works when applied to the entire card. The red accents on the edges look nice, but to me, they don’t immediately strike me as features from a razor blade.
