Greg, welcome to the Forum and Happy new year...
if you have the 'staninless' version, they are sometimes very "tough" to get out the first time, (burrs, rough, whatever..) but it does and will pop out,,,,, last one we did for a guy have to put the blade in a bench vise ,push the plunger in and still had to "tap" it out.....can you say need 3 hands??? :roll:
