Nice Lambsfoot Steve. Wright's still use that exact same blade blank, do the same pattern, use the same stamp. Even the Sambar scales do not mean that it was made before the Indian Government ban on stag exports, it took a while for that ban to bite in Sheffield, and even now, Wright's occasionally turn out one of those 'Candle-end' models with Sambar. I got one last year. The stag has mellowed, but the Sambar they're using was often cut decades ago for cutlery handles, and the construction (number of pins) is exactly the same as today. So, your knife could be 5 years old, 10 years old, or 20 years old. You could perhaps hazard a guess from the amount of wear it has had, but that might merely indicate that it was used a lot, rather than that it was used over a longer period. In terms of the construction, I think that Wright's have pulled their socks up a lot in terms of QC, but that is only over the past couple of years, so again, the quality of construction tells us little. I'm assuming it has brass liners, if not, that would indicate an older knife. My guess would be that it was made within the past 20 years, but it's hard to say more than that, particularly without examining it. It could be older, but it isn't an old knife. It might help if you said where you acquired the knife
