===Petersen Type M===
{{Type| Similar to type K, but shorter, and they have the widest part of the blade further towards the tip than type K's. These date mostly to the C11th. [PETERSEN 1919] Fuglesang has redefined the difference between types K and M by measuring the distance from the mouth of the socket to the widest part of the blade (the shoulder). [FUGLESANG 1980]<br>
:Type K: 1:3 to 1:3.8 <br>
:Type K/M: 1:2.4 to 1:3 <br>
