However, the arrowheads used in the Bane test were made of steel, while research by the Royal Armouries and the Historical Metallurgy Society suggests that a majority of medieval arrowheads were made from wrought iron instead. Computer analysis by Mariusz Magier, Adrian Nowak and others published in 2017 found that heavy bodkin point arrows could penetrate typical plate armour of the time at . The depth of penetration would be slight at that range but would increase as the range closed or against armour lesser than the best quality available at the time. In August 2019, the YouTube channel 'Tod's Workshop', together with historian Tobias Capwell (curator at the Wallace collection), Joe Gibbs (archer), Will Sherman (fletcher), and Kevin Legg (armourer) ran a practical test using a reproduction of a 15th century plate breastplate over a chainmail and gambeson against a 160 lbf (710 N) longbow. Both wrought iron and case hardened arrows were fired at the target from a distance of 25 meters. In contrast to the earlier computer analysis, neither arrow type successfully penetrated the breastplate. References External links Making a Bodkin Mary Rose historical ship.
