When tested with an XRF instrument the Royal Doulton brand knife (purchased new c. 2009) pictured here had the following readings…
Reading on blade

- Nickel (Ni): 1,203 +/- 391 ppm
- Iron (Fe): 873,900 +/- 2000 ppm
- Vanadium (V): 656 +/- 169 ppm
- Manganese (Mn): 5,915 +/- 1,125
Reading on handle:
- Chromium (Cr): 121,900 +/- 1,000 ppm
- Bromine (Br): 36 +/- 17 ppm
- Copper (Cu): 826 +/- 243 ppm
- Nickel (Ni): 1,459 +/- 396 ppm

Tests results are science-based and replicable. All tests are done for a minimum of 60 seconds unless otherwise noted. Tests are repeated multiple times to confirm the results, using a freshly calibrated XRF instrument testing in consumer goods mode. Metals not listed in above test results sets were not detected with testing done in “consumer goods mode”.
