For my use the scanner is fine for papers & what I cannot scan I will photograph the best knife photos are out doors the one I did was with natural light I also think in general the pictures are best in cloudy conditions since the light is diffused so no problems with glare.
Your scan pictures are very good.

Good question Leo, I'll ask the webmaster how it's set. Those are 1500px wide.

I have been setting mine at 500 pixels max width or height whichever is greater I kept finding my images were too large so bored of that I opted for that but they miss a lot at 500 pixels especially when I have taken the trouble to photograph using a real camera over the iPhone.

I've been poking around a bit more.

Naive me. I assumed that knifemakers would, these days, already have these 3D files of their knives and that, as sharpeners, they would likely be available to us. Wrong.

What I found out is that the knifemakers I got in touch with who had files guarded them as corporate "secrets" and weren't even close to considering giving the files away. After being told "no way" by SOG & Buck, I didn't try to contact any custom makers. I did read some opinions on other blade forums and they all doubted there would be ease of access freely given to the files.

Afterall, who would want end users printing out their own modified Bob Loveless or even a Gryptillian? So, I kind of see the makers point of view.

I would love a Loveless but the 3D printing technology isn't up to printing in the quality of steel required. So, scanning is ahead of direct, local printing.

It also seems a losing battle with the ease of access almost anyone has to 3D scanning & printing these days. From what I saw, $50 - $100 to scan a knife sized object -- a little spendy but still accessible.

Anyway, it's been an interesting little side jaunt on this fascinating thread.... looking forward to the next instalment....

Heard back from our webmaster:

"1mb 800px x 800px"

Oddly, I can always upload pictures that are wider than 800px.

Anthony - are the above images useful to you or should I try something else? Also, do you have any requests for knives you'd like to profile?
