Hey Marc: I went through every page.
My faves first:
VERY clean and modern with minimalist white. It looks current.
Home page photo: Great dramatic image.
Good clear double spaced text and a VERY pleasing grey font. I could read nicely. (What is that font? So smart.)
The Photo Gallery format is medium 'thumbs' to LARGE. Just right!
You ACTUALLY have some knives available. How about that!
Your knives and sheaths are spectacular. Immediately apparent.
Minimalist contact page: Get right to the point.
First person dialog. You are talking to me directly. Very personal. ( I dislike third-person dialogs:
Marc has been making knives for 10 years... etc.)
Your photography is professional and VERY satisfying. You clearly spent time creating a light tent and quality lighting to showcase your superb work. (I've seen, you've seen, we've ALL seen, ummmmmm, far worse from makers..

)

I have some subjective points of things I'd prefer and didn't like:
The home page photo is
huge. I find it's a bit TOO large. I have a 27" hi-res screen, too.
The link menu bars on top were
lost on me at first. I'd wish you'd increase those fonts. I know it's minimal, but for me they get lost. I'd grow them a bit.
For years and years I have ALWAYS wished for a nice clear photo of the
maker on their 'About me' page. This is where the maker is talking to me directly. (In your case you are also talking in first person, and that much more I want to SEE the person I'm talking with, not tools.) Your header photo is not enough. I"d ask you for a direct looking-at-the-viewer shot from your workbench. That's me.
Nowhere on the site does it say your full name. I only know your name is
Marc from here and on Facebook. You may be doing this on purpose, but.... why?
Your pricing is described well, but you are generalizing. In your conversation you are lumping yourself in with ALL 'Custom' makers. Here's where you are distinct. Bring it back to YOU.
Pricing:
'Price on Request' This sure will weed out the tire kickers, but I am uncomfortable in spending time in a dialog to see if you and my wallet are even close. I want answers, not more questions!
The blocks of text, although very readable are, from a grammar standpoint, needing paragraphs. This would take away from the
look. You have to decide which is more important: a look, or the message read clearly.
All of my comments are subjective. Thanks for asking. VERY good work!
Process and source: Did you work it from a template? How much time did you spend? (From one who spent WEEKS years ago creating mine!)
