Before we begin, it's important to note that all of our hidden blade ring sizes are based on the US mens ring sizes. We do also recommend sizing up 1 size as your finger can swell slightly during use of the blade. Lastly if you do not see your ring size as an available option eg; 15,16,17 etc, please contact us to discuss custom sizing options. Now lets begin!

Step 1: Gather Your Materials
You’ll need:
- A strip of paper or a piece of non-stretchy string (around 6 inches / 15 cm long)
- A pen or pencil
- A ruler
- The men's US ring size chart (downloadable online or you can use our reference chart)

Step 2: Measure Your Finger
1. Wrap the Paper or String: Wrap the paper strip or string around the base of the finger you want to measure. Make sure it's snug but not tight, as rings should feel comfortable.

2. Mark the Paper or String: Use the pen to mark where the paper or string overlaps at a complete circle around your finger.

3. Measure the Length: Lay the marked strip or string flat and measure the length from the end to the marked point with a ruler in millimeters.

Step 3: Find Your Ring Size Using the Chart
1. Match Your Measurement: Use the men’s US ring size chart and locate the ring size that corresponds to your finger circumference measurement in millimeters.

2. Select the Closest Size: Choose the size closest to your measurement. If you're between sizes, we often recommended to go up a size, as fingers can swell slightly throughout the day and during use of the blade.

Additional Tips
- Measure When Fingers Are Warm: Cold temperatures can shrink finger size, so measure when your hands are warm for the most accurate fit.
- Try Multiple Times: For accuracy, repeat the measurement two or three times to confirm the fit.
- If You Are Still Unsure Of Your Ring Size: You can always request additional ring sizes in the notes section at checkout.

And that’s it! You have now found the ring size for your hidden blade, welcome to the brotherhood!
