To see how much the price of a product increased, go to
https://www.usinflationcalculator.com/ and type in the price the item sold for in the year you bought it and it will show you how much it would cost in the current year.
Then go to a site that sells the product and compare the prices.
I paid $70.00 for a Carbon V Recon Tanto in 1997 and in current dollars it would be $123.74. This would make it maybe three or four times the price of the current SK5 version and about as much as the current San Mai III version, and a bit less than the old Carbon V Recon Tantos sold on auction sites.
I don't know how much the SRK sold for in 1997 but remember it was a little less than the Recon Tanto, and the auction prices I checked after reading this thread were between $140.00 and $300.00, so a new condition SRK in Carbon V, judging from what that site lists them at today (it could change next week), ranges from just a little more than their original cost to over twice the original cost.
