Had a problem with mine , the blade cap iron would not lock in position but kept coming loose. E-mailed veritas in Canada and within 1/2 hour had a reply saying replacement was in post from Lee Valley tools their UK agent , arrived today , great service.
It must be in here somewhere :--
Ha Ha it was just hiding :--
Seems that the part has been modified , perhaps others have had the same problem, but full marks to Veritas for their response.
