Ding Dong Handwritten Font is a cool and modern straight handwritten font by Vlad Cristea. It's unique handwritten look makes it perfect for use in all of your design projects. I would file this font under the "neutral" category in our Make the Best With Less blog post.

• This font comes in 3mm, 4mm, 5mm, and 6.5mm
• Shank size: 1/4" for 3mm, 4mm, 5mm, 5/16" for 6.5mm
• NOTE: THE UPPERCASE IS SIGNIFICANTLY LARGER THAN THE LOWERCASE.
• The sizing of this font is based on the UPPERCASE SET - not the lowercase.
  

My two cents:

• This font is sized according to the specifications of the foundry. 
• The uppercase sizes are the sizes of the font, and the lowercase is nearly one-third the size of the uppercase. 
• That puts the 3mm Uppercase set at 3mm, and the lowercase set for 3mm is actually about 1.5mm. 
• This font will be excellent in stainless steel (and all metals) -- and because the lowercase is SO MUCH SMALLER than the uppercase, a gentle TAP with your hammer will suffice. 
• Too much of a hammer-strike could make the lowercase illegible, and should that happen to you, try hammering a little softer.
